Use the Window > Preferences dialog page to set the preferences of RT-LAB.

The value of these parameters are used when a new model is created. If you change a property from the Preference page, each new model will inherit settings from the Properties defined in the Preference page but existing models stay unchanged.

Capabilities Preference Page

Window > Preferences > RT-LAB > Capabilities

The capabilities preference page allows you to enable or disable various product components of RT-LAB such as Operator or Developer environments. By default, no capabilities are active and only the basic functionalities of RT-LAB are active.

Operator	This capability enables all features that allow the user to manage consoles and make some changes to the parameters and aliases of the models. It enables all components making data acquisition and monitoring and also basic operations on the simulator as loading, executing, pausing or resetting the models. (default value=false)
Developer	This capability enables all features related to the development of models, scripts, and codes. It also enables all features of the operator capabilities. (default value=false)
Advanced User	This capability enables all product components including operator and developer capabilities. Moreover, it also enables other unclassified features related to Eclipse and external plugins. (default value=false)

Compiler and Linker Preference Page

Window > Preferences > RT-LAB > Development > Compiler

The value of these parameters is used when a new model is created. If you change a property from Preference page, each new model inherits settings from Properties defined in the Preference page but the existing models stay unchanged.

The Restore Defaults button	Enables the user to restore the defaults value of the parameters.
Sources	Names of source files to be compiled in addition to the code generated by RTW. Used to incorporate user-written code into the model executable (e.g. file1.c file2.c file3.c)
Includes	Target path(s) where user include files can be found. Used to search for include files required to compile user-written code, when the include files do not reside in already-searched paths.
Libraries	Names of user-specified libraries to be used when incorporating user-written code, in addition to the standard system libraries (MATLAB and RT-LAB).
Library path	Target path(s) where user libraries can be found. Used to search for libraries other than the MATLAB and RT-LAB libraries when incorporating user-written code.
Compiler command	User command to be called on the target during the compilation process.

Monitoring Preference Page

Window > Preferences > RT-LAB > Diagnostic > Monitoring

The value of these parameters is used when a new model is created. If you change a property from Preference page, each new model will inherit from Properties defined into Preference page but the existing models will stay unchanged.

Enable monitoring	Enables or disables the monitoring during the execution of the model. (default value=true)
Display controller in operating system task bar	Displays RT-LAB Controller application in the taskbar. Unchecked by default. (default value=false)
Display warning when disk space is lower than [Mo]	When checked, a warning message is displayed when the disk space is lower than the value specified. (default value=false)
Target display information	Represents the amount of information that is displayed in the display window during load and execution. Setting the value from MINIMAL to EXHAUSTIVE allows the user to retrieve more information about communication and I/Os initialization for example. This can be used to debug unexpected model behaviors. (default value=minimal)
Message precision factor (us)	Defines the precision of the timer reporting the time required to perform one calculation step in microseconds. The default value is 0 (no printout). Value=1 prints the step size of the model every 1,000,000 steps with a precision of 1 μs. Value=100 prints the model’s step size every 10,000 steps with a precision of 100 μs and so on. (default value=0)

Debugging Preference Page

Window > Preferences > RT-LAB > Diagnostic > Debugging

The value of these parameters are used when a new model is created. If you change a property from Preference page, each new model will inherit from Properties defined into Preference page but the existing models will stay unchanged.

Enable controller log (s)	Creates a file called Controller.log in the RTLAB_ROOT\common\bin folder for debugging use. This file reports all operations perform on the model during the life-cycle of your project. Note also that it reports also other internal operation related to the controller of your project. Unchecked by default. (default value=false)
Enable extended timeout	All timeouts are extended when this option is enabled. It is typically used when debugging the model. (default value=false)
Enable watchdog	Enables or disables the Watchdog functionality. The Watchdog ensures that all nodes are running normally. There are as many watchdogs as there as computation subsystems in the model. At regular user-defined time intervals, the watchdog verifies that the model is still running and that processes are still active. If an error occurs, the watchdog stops the simulation. This option is not available on Windows target.(default value=true)
Watchdog timeout [ms]	The regular user-defined time interval the watchdog verifies the model is still running. 5000 ms by default. (default value=5000)
Compile model in debug	When this option is enabled, the compiler's optimization options are removed and replaced by debug options during model compilation. This option is useful when debugging a model. (default value=false)

Environment Variables Preference Page

Window > Preferences > RT-LAB > Execution > Environment Variables

The value of these parameters are used when a new model is created. If you change a property from Preference page, each new model will inherit from Properties defined into Preference page but the existing models will stay unchanged.

Name	Name of the user variable.
Value	Value of the user variable.
Description	Description of the user variable.

Files Transfers Preference Page

Window > Preferences > RT-LAB > Execution > File

The value of these parameters is used when a new model is created. If you change a property from Preference page, each new model will inherit from Properties defined into Preference page but the existing models will stay unchanged.

File retrieval root directory	Directory where the files retrieved by RT-LAB after the model execution is copied.
Enable automatic file retrieval	When this option is enabled, RT-LAB retrieves files generated by the model simulation on the target nodes and transfers them to the host computer. (default value=true)
Enable file retrieval during simulation	If this option is enabled, RT-LAB retrieves the files generated by the model simulation as soon as they are created on the target. If this option is disabled, RT-LAB will retrieve those files after the model resets.
Build intermediate tree on file retrieval	Specifies if intermediate folders are generated or not in the retrieved directory. (default value=true)
Display notifications	Displays a pop-up notification each time a file is retrieved: Clicking on the notification opens the file with an appropriate editor or with Matlab, depending on the file extension.
Do not display notifications at reset	Prevents RT-LAB from displaying notifications when files are retrieved after a model has been reset. This is useful when many files are retrieved, since there is one notification per file.

Performance Preference Page

Window > Preferences > RT-LAB > Execution > Performance

The value of these parameters are used when a new model is created. If you change a property from Preference page, each new model will inherit from Properties defined into Preference page but the existing models will stay unchanged.

Enable detection of overruns

(Only applies to models ran in hardware/software synchronized modes.) When this parameter is not checked, RT-LAB does not detect overruns.

When this parameter is checked, RT-LAB detects overruns and performs the action specified in the Action to perform on overruns field. This property has no effect in simulation mode. (default value=true)

Perform action after N overruns

Performs the action specified in the Action to perform on overruns field when the number of overruns detected by RT-LAB reaches this number. (Only applies when Action to perform on overruns is set to Reset or Pause.)

Default value=10

Action to perform on overruns

Type of action to perform when overruns are detected.

Default value=Continue

Here are the available types:

Continue	No action is performed; Number of overruns will simply be displayed during the next pause/reset of the model.
Reset	A reset of the model is performed when the number of overruns reaches the value of the Perform action after N overruns field.
Pause	A pause of the model is executed when the number of overruns reaches the value of the Perform action after N overruns field.
Number of steps without overruns	Prevents RT-LAB to detect overruns during the first steps of simulation. (default value=10)

Real-time Preference Page

Window > Preferences > RT-LAB > Execution > Real-Time

The value of these parameters are used when a new model is created. If you change a property from the Preferences page, each new model inherits from Properties defined in the Preference page but the existing models stay unchanged.

Note: 'Simulation with low priority' mode is only available when working with a Windows target.
Default target Platform	Allows the user to choose the target platform on which to run the simulation (OPAL-RTLinux (x86-based) or Windows system). Default value=OPAL-RTLinux x86-based.
Real-time simulation mode	Enables the user to define how the model’s simulation can be executed on an OPAL-RTLinux (x86-based) or Windows system. Default value=Software synchronized.
Simulation	In this mode, the model is not synchronized; the model starts a new computation step as soon as the previous one is completed (the model runs as fast as possible).
Simulation with low priority	this simulation mode can be used to run a simulation in the background while working with other applications on the same computer.
Software Synchronized	In this mode, real-time synchronization of the entire simulation is achieved by the OS, using the CPU clock as a reference. Depending on the resolution available on the OS, some sampling times may not be obtained using this mode.
Hardware Synchronized	In this mode, an I/O board clock is used to synchronize the entire simulation.
Real-time communication link type	Sets the target cluster’s communication medium. Default value=UDP/IP. Here are the available choices for each target platform. Windows: UDP/IP. OPAL-RTLinux (x86-based): UDP/IP or Dolphin.
Time Factor:	This value, when multiplied by the model’s basic calculation step (or fixed step size), supplies the final calculation step for the system. The time factor can only be changed when the simulation execution is paused and is only available in Synchronized (hardware/software) mode. (default value=1.0)
Note: This parameter enables you to change the I/O acquisition speed. Because the model always uses the basic calculation step, changing the time factor for the I/O may give results that differ from the offline simulation. This parameter should be used only to determine the simulation’s minimum calculation step. Once this step is determined, this parameter must be brought back to a value of 1. The model’s basic calculation step must be updated accordingly by setting the correct value in the Simulink model and by recompiling it.
Stop time	This value (in seconds) specifies when the model will stop. If the value is Infinity, the model executes forever. You don’t need to recompile the model to apply a new value. (default value=Infinity)
Pause time	This value (in seconds) specifies when the model will pause. If the value is Infinity, the model executes until a reset is done except if a stop time is specified. (default value=Infinity)

Hardware Preference Page

Window > Preferences > RT-LAB > Hardware

The values of these parameters are used when a new model is created. If you change a property from the Preferences page, each new model inherits from Properties defined into Preference page but the existing models will stay unchanged.

Reset model on I/O board missing

When the option is checked and the model is loaded, RT-LAB stops loading and generates an error, if some I/O boards required by the model are not detected on the target(s).

RT-LAB generates only a warning if this setting is unchecked. Note that only a few I/O boards (mainly the Opal-RT TestDrive boards) support this option. Most I/O blocks force a reset of the model if the boards are not detected at load time. Default value=true.

Abort compilation on bitstream missing

When option is enabled, if some bitstreams required by a model are not present in the model directory, RT-LAB stops the compilation and generates an error.

RT-LAB generates only a warning if this setting is disabled. Default value=false.

Simulation Tools Preference Page

Window > Preferences > RT-LAB > Simulation Tools

The value of these parameters are used when a new model is created. If you change a property from Preference page, each new model inherits from Properties defined in the Preference page but the existing models stay unchanged.

Matlab command before opening model	Matlab command to execute before opening the model. For example. MyInitFile.m, where MyInitFile includes commands that initialize model variables.
Matlab command after opening model	Matlab command to execute after opening the model. For example, MyInitFile.m, where MyInitFile includes commands that initialize model variables.
Handle console automatically	Enables the console to be automatically opened and closed, when a model is Loaded or Reset. The console starts automatically at the first model’s execution. Default value=false.

EMTP Preference Page

Window > Preferences > RT-LAB > Simulation Tools > EMTP

The value of these parameters are used when a new model is created. If you change a property from Preference page, each new model inherits Properties defined in Preference page but the existing models stay unchanged.

EMTP-Works/EMTP-RV Installation folder	Path where the EMPT tool is installed.

MATLAB Preference Page

Window > Preferences > RT-LAB > Simulation Tools > Matlab

The value of these parameters are used when a new model is created. If you change a property from Preference page, each new model inherits Properties defined in Preference page but the existing models stay unchanged.

Use same Matlab version than model	Use same Matlab version as model to open and compile Simulink mode. If Matlab version of model is not supported or not installed, use Current Matlab version. Default value=unchecked. Note: In an opened project, if a model is saved in a new Matlab version, the new Matlab version will be used next time your project is opened.
Current Matlab version	Matlab version used to open and compile Simulink models. Note: this setting will be changed if the user opens the model by choosing Edit with and a new Matlab version. Default value is the latest installed, compatible version
Matlab and Simulink target root directory	Path to be used instead of /usr/matlab to find the MATLAB include and source files. RT-LAB supports multiple versions of Matlab by keeping copies of previous versions in paths other than /usr/matlab. Automatic setting means the target path is automatically set based on the MATLAB version used on the Command Station. (default value=automatic)
RTW template make file (TMF)	Specifies which template makefile to use during the compilation. When Automatic is selected, the template makefile corresponding to MATLAB version is automatically selected. This option is available for SIMULINK models only. (default value=automatic)
RTW target language compiler file (TLC)	Specifies which TLC file to use during the compilation. When Automatic is selected, the TLC file corresponding to the MATLAB version is automatically selected. This option is available for SIMULINK models only. (default value=automatic)

RT-LAB Preference Page

Window > Preferences > RT-LAB > Simulation Tools > RT-LAB

The value of these parameters is used when a new model is created. If you change a property from the Preference page, each new model inherits from Properties defined in the Preference page but the existing models stay unchanged.

Development targets OPAL-RTLinux (x86-based)

Identifies the target node where the compilation is done. Target nodes must be defined in the workbench, by using the New Target wizard, before the development node can be chosen.

Target root directory

Path to find the RT-LAB executables include files and libraries or the target nodes. This allows previous versions of RT-LAB to be used side-by-side with newer versions.
The set-up script makes the last version installed the default system but, this option can be used to specify a version based on its path.

Automatic setting means the target path is automatically set based on the last installed RT-LAB version. (default value=Automatic)

Target Detection Preference Page

Window > Preferences > RT-LAB > Target Detection

Enable target detection	Uncheck this option to completely disable automatic target detection. Target detection can still be manually done by right-clicking on the Targets item of the Project Explorer and selecting the Discover targets menu.
Display notifications	Displays a popup notification each time a target is detected: Clicking on the notification opens the Detected Targets Wizard. Automatically add new targets to the workbench: New targets are added to the workbench as soon as they are detected.
Ignored targets	If you do not want to be notified when a particular target is connected to the network, simply add its IP address to this table. This table is also automatically populated by the Detected Targets Wizard.
Detection ranges	Here you can limit the target detection to some IP addresses by defining ranges. Any target outside these ranges will not be detected by RT-LAB. Note: Ignored targets and targets outside the detection range can still be used in the Workbench, but you will have to add them manually by using the New Target wizard.

Initially show ancestor pane	Sometimes you want to compare two versions of a resource with the previous version from which they were both derived. This is called their common ancestor, and it appears in its own comparison pane during a three-way compare. Turn this option on if you want the ancestor pane to always appear at the start of a comparison.
Show pseudo conflicts	Displays pseudo conflicts, which occur when two developers make the same change (for example, both add or remove the exact same line of code or comment). Turn this option on if you want pseudo conflicts to appear in compare browsers.
Connect ranges with single line	Controls whether differing ranges are visually connected by a single line or a range delimited by two lines.
Highlight individual changes	Controls whether the individual changes inside conflicts are highlighted.
When the end/beginning is reached while navigating an element	Use this option to configure what occurs when the end/beginning is reached while navigating an element.
Prompt	If this option is on and you selected to compare a single element you will be asked whether you want to go to the beginning/end of the element after the end/beginning is reached. If you are comparing two or more elements you will be asked whether you want to go to the beginning/end of the current element or to go to the next/previous element. Moreover, if you choose to remember your decision, this option will be changed to one of the below respectively.
Loop back to the beginning/end	When this option is on, the selection will be moved back to the beginning/end after you reach the end/beginning of an element.
Go to the next/previous element	If you are comparing two or more elements and this option is on after you reach the end/beginning of an element the next/previous element will be opened.

Content Types Preference Page

The General > Content Types preference page enables you to edit content types and their associated file names and character sets. You can also associate arbitrary file names or file extensions with content types. A content type acts as a description of a certain class of files (for instance, XML files). RT-LAB uses this description in various scenarios, such as editor look-ups and file comparisons.

Window > Preferences > General > Content Types

By selecting a content type in the topmost tree, you can alter the file names and extensions associated with it.

Note: Certain items are marked as locked. An item is locked if it is one of the associations provided by the plug-in that declares the content type. In other words, you can remove only user-contributed associations.
Adding an association is as simple as clicking Add.... A dialog prompts you to enter the file name or extension.
In addition to adding and removing file names or extensions, you can also set the default encoding for a given content type. To do this, simply enter the encoding name in the provided field and click Update.

Editors preference page

General > Editors

Size of recently opened files list	Each file opened in an editor is stored in a list of recently used files in the File menu. This option controls the number of files displayed in that list.
Show multiple editor tabs	Specifies whether you wish to show multiple editor tabs. If off, editor workbooks have one large tab and all non-visible editors are accessible only from the chevron.
Close editors automatically	Specifies whether or not to re-use editors in the Workbench. If on, you may specify the number of editors to use before they are recycled (the default is 8). You can also specify if a prompt dialog should be opened or if a new editor should be opened when all editors are dirty (have unsaved changes). Once it is turned on, the Pin Editor action is added to the toolbar and editor tab menu. Pinned editors are not recycled.

File Associations Preference Page

General > Editors > File Associations

File Types List

Add...	Adds a new file or file type (extension) to the predefined list. In the resulting New File Type dialog, type the name of a file or a file extension. If you are adding a file extension, you must type either a dot or a . before the file type (e.g., .xml or .xml as opposed to simply xml).
Remove	Removes the selected file type from the list

Associated Editors List

Add...	Adds a new editor to the list of editors associated with the file type selected above. In the resulting Editor Selection dialog, you can choose an editor to launch either inside the Workbench (internal) or outside the Workbench (external); click Browse to locate an editor yourself if the editor you want is not displayed in the list.
Remove	Removes the association between an editor and the file type selected above. Note: Any editor that is bound by content type may not be removed from this list. Currently, there is no mechanism available to remove these editors.
Default	Sets the selected editor as the default editor for the file type selected above. The editor moves to the top of the Associated Editors list to indicate that it is the default editor for that file type.

Help Preferences

Use external browsers	If embedded web browser is supported on your system, help window uses an embedded help browser to display help contents, whenever possible, and this option is available. Select it to force help to use external browsers. Use Web Browser preference page to select a browser to use.
Open window context help	Determines whether the window context help are opened in a dynamic help view or in a pop-up.
Open dialog context help	Determines whether the dialog context help will be opened in a dynamic help section of help view or in a pop-up.
Open help view documents	Determines whether the documents selected in the help view are opened in place or in the editor area. Note: Selection performed on this page can affect how the help view is presented. If the selected browser is not fully compatible with Internet Explorer or Mozilla, or has JavaScript disabled, the help view shown in the browser might be a simplified version.

General Preference Page

Each Workbench contains one or more perspectives. Perspectives contain views and editors and control what appears in certain menus and toolbars.

Always run in background	Turn this option on to perform long-running operations in the background without blocking you from doing other work.
Keep next/previous part dialog open	If this option is turned on then the editor and view cycle dialogs will remain open when their activation key is let go. Normally the dialog closes as soon as the key combination is released.
Show Heap Status	Turn this option on to display an indicator showing information about current Java heap usage.
Open mode...	You can select one of the following methods for opening resources: Double-click: Single clicking a resource selects it and double-clicking it opens it in an editor. Single-click (Select on hover): Hovering the mouse cursor over the resource selects it and clicking it once opens it in an editor. Single-click (Open when using arrow keys): Selecting a resource with the arrow keys opens it in an editor. Note: Depending on which view has focus, selecting and opening a resource may have different behavior.

Help Content Preference Page

Port	If Use default port is selected, port 80 will be used to access remote content on the host. To use any other port the Use port option must be selected and the correct port must be specified in the text field.

Keys Preference Page

The function of the keyboard can be extensively customized in RT-LAB using the General > Keys preference page. Within RT-LAB, keystrokes and key sequences are assigned to invoke particular commands.

Keystrokes, Key Sequences, and Key Bindings

A keystroke is the pressing of a key on the keyboard, while optionally holding down one or more of these modifier keys: Ctrl, Alt or Shift. For example, holding down Ctrl then pressing A produces the keystroke Ctrl+A. The pressing of the modifier keys themselves do not constitute keystrokes.
A key sequence is one or more keystrokes. Traditionally, Emacs assigned two or three keystroke key sequences to particular commands. For example, the normal key sequence assigned to Close All in emacs is Ctrl+X Ctrl+C. To enter this key sequence, one presses the keystroke Ctrl+X followed by the keystroke Ctrl+C. While RT-LAB supports key sequences of arbitrary lengths, it is recommended that keyboard shortcuts be four keystrokes in length (or less).
A key binding is the assignment of a key sequence to a command.

A scheme is a set of bindings.

RT-LAB includes three schemes:

Default
RT-LAB (extends Default)
Emacs (extends Default)

The Default scheme contains a general set of bindings, in many cases recognizable as traditional key sequences for well-known commands. For instance, Ctrl+A is assigned to Select All, and Ctrl+S is assigned to Save.

It is important to understand why the RT-LAB scheme says that it 'extends Default'. The RT-LAB scheme is not a complete set of bindings like the Default scheme. Rather, it borrows from the Default scheme where possible, only defining explicit RT-LAB-style bindings where they vary from the Default scheme.

Choose the scheme you are most comfortable with by changing the 'Scheme' setting on the keys preference page. If you choose the Default scheme, all RT-LAB bindings are ignored. If you choose the RT-LAB scheme, explicit RT-LAB-style key sequence assignments take precedence over any conflicting assignments in the Default scheme.

Contexts

Key bindings can vary based on the current context of RT-LAB.

Sometimes the active part might be a text editor, for instance, where a different set of key sequence assignments may be more appropriate than if the active part was an html file editor. This context is usually determined by the active part, but it can be influenced by the active window or dialog as well.

If the active part does not choose a particular context, the workbench will set the active context to In Windows.

RT-LAB includes a number of different contexts.

Some examples are:

In Dialogs and Windows
In Windows (extends In Dialogs and Windows)
In Dialogs (extends In Dialogs and Windows)
Editing Text (extends In Windows)
Debugging (extends In Windows)

In Console

Much like configurations, contexts can extend other contexts.

Note: It is not recommended to promote a key binding to a context which it extends. For example, it is not recommended to move an Editing Text key binding to the In Dialogs and Windows context. This may have unexpected results.

Some key bindings work in dialogs. Those key bindings are assigned to the In Dialogs and Windows context. One example of such a key binding is the key binding for cut.

Users can change these key bindings. For example, you can have Ctrl+X as cut in dialogs, but Ctrl+W as cut in windows.

Customizing Key Bindings

With multi-stroke key sequences, schemes, and contexts, there are a lot of things to keep in mind when customizing key bindings. To make things easier, all key customization is done on the General > Keys preference page.

In this example, we want to bind CTRL+5 to the About command. By default, the keys preference page will show you all possible keybindings. You can see the About command listed in the Help category. You can bind the command by putting focus in the Binding text box and pressing CTRL and 5 like you would if you were executing the command.
When you type CTRL+5 you have created a binding for About. The right-most column will indicate that this is a user binding by displaying a U. If there was a conflict with another key, this column would also display a C. The binding will be in the default context, In Windows. You can now use the
When combo box to change the key binding context (for example, to move this binding to Editing Text).
If you wanted to add a second key binding to About, you can use the Copy Command button to create a second command entry for you to bind another key to. If you want to delete a binding, you can either use the Remove Binding button or simply give focus to the Binding text box and hit Backspace.

The Dynamic Nature of Key bindings

Key bindings are provided by plug-ins, and in RT-LAB, plug-ins can be added or removed. This can cause key bindings declared by these plug-ins to be added or removed. RT-LAB stores custom key bindings in a way to compensate for this. Consider the example above where CTRL+6 was assigned to About in the Default scheme. Say you install a new plug-in that assigns CTRL+6 to a particular command. RT-LAB will preserve your assignment to About.

Conflict Resolution

There are only a finite number of simple, common keystrokes available to assign to a multitude of commands. We have seen that scheme, context and platform all partition key sequence assignments into domains where they don't conflict with one another. Consider the case for Ctrl+B above if contexts did not exist.

One plug-in would assign Ctrl+B to Build, the other plug-in would assign Ctrl+B to Make Bold Text. How would RT-LAB properly resolve this conflict?
Though conflicts are drastically reduced by employing the above mechanisms, they can still occur. Two plug-ins, independent of one another, could assign the same key sequence to different commands with the same context, scheme, platform, and locale. Consider if a plug-in assigned Ctrl+F4 in the In Windows context and Default scheme to one of its commands. This directly conflicts with RT-LAB assigning Ctrl+F4 to the close command in the same context and scheme.
This is a conflict.
It wouldn't be proper to invoke both commands, nor would it be proper to simply choose one of the two commands to receive the keystroke. We pop up the Key Assist Dialog with the conflicting commands and allow the user to select one. The Key Assist Dialog is the same dialog that displays command choices for multiple keystroke key bindings.
For example, if 2 commands were bound to F12 you might see a small dialog with two choices.
If the user sets a keybinding and creates a conflict, the conflicting bindings will be displayed in the conflicts list. This can be used to navigate between conflicting keybindings so that they can be changed.
These types of conflicts can be resolved by explicitly assigning the key sequence to one of the commands, or remove it from the other.
Another type of conflict can be caused by multiple-keystroke key sequences. For example, in the Emacs scheme, there are many multiple-keystroke key sequences beginning with the keystroke Ctrl+X. Ctrl+X K is assigned to Close. Ctrl+X H is assigned to Select All.
As previously mentioned, the Emacs scheme borrows key bindings from the Default scheme. In the
default scheme, Ctrl+X is assigned to Cut.
Though the Emacs scheme doesn't explicitly redefine Ctrl+X, pressing Ctrl+X is required as part of many of its key bindings. In the Emacs scheme, when one presses Ctrl+X, one is half way to entering one of many possible assigned key sequences.
One would not expect the Cut action to be invoked at this time.
For this type of conflict, the rule is that the Ctrl+X key sequence assigned to Cut would be ignored.
Otherwise, it would not be possible to complete many of the key bindings in the Emacs configuration.

Label Decorations Preference Page

Label Decorations allow additional information to be displayed in an item's label and icon.

General > Appearance > Label Decorations

Linked Resources Preference Page

General > Workspace > Linked Resources

The preference Enable linked resources is used to globally enable or disable the linked resource feature for the entire workspace. By default, linked resources are enabled. If you disable
linked resources, then you will not be able to create any new linked resources or import existing projects that contain linked resources.

Not all versions of the workbench support linked resources and recognize them as such. You may not want to use linked resources if you plan to share your workspace data with other users. Disable this preference if they will not be able to work with linked resources.

The remainder of this page is for defining path variables that are used when creating linked resources.

Use the New button to define new variables, the Edit button to change the value of an existing variable, and the Remove button to get rid of an existing variable. Note if you change a path variable that is currently in use, you will need to perform a local refresh on those projects to discover what is different in the file system. You can refresh a resource by opening one of the navigation views' context menu for that resource and selecting Refresh. It is not recommended that you remove a path variable that is currently in use.

Local History Preference Page

Cheat Sheets

RT-LAB provides cheat sheets to guide you through some of its application processes. Each cheat sheet is designed to help you complete some task, and lists the sequence of steps required to help you achieve that goal. As you progress from one step to the next, the cheat sheet automatically launches the required tools for you.

If there is a manual step in the process, the step tells you to perform the task and click a button in the cheat sheet to move on to the next step.

Launching a cheat sheet

To launch a cheat sheet from the Workbench

Select Help > Cheat Sheets from the menu bar.
The available cheat sheets are listed, select one and click OK. Alternately, if you know the location of a cheat sheet content file on your file system or on the web you can enter its path.

The cheat sheet opens as a view. At any time, only one cheat sheet is open and active. When you launch a cheat sheet, any open cheat sheet is closed before the new one is opened. The completion status of the closed cheat sheet is saved.

Collapses all	Collapses all the expanded steps except the current step or expands steps to the last expanded state. Click to toggle between these two states.
Select	Allows you to select and open another cheat sheet. The completion status of the active cheat sheet is saved. Then, the active cheat sheet is closed and the selected cheat sheet is opened.
Hide	Hides the cheat sheet.
Save	Saves the completion status of the active cheat sheet and closes it.

Note: Some cheat sheets can also be launched from the Welcome page by first selecting Tutorials and then selecting one of the tutorials.

Starting the cheat sheet	Each cheat sheet has a list of steps and it always begins with an Introduction step. When you launch a fresh cheat sheet, the Introduction step is expanded so that you can read a brief description of the cheat sheet. To start working with the cheat sheet, click Click to Begin in that step. The next step is expanded and highlighted. You should also see one or more actions buttons, such as Click to Perform in the highlighted step. You can now begin working through the tasks using the cheat sheet. At any time, the only highlighted step in the cheat sheet is the current step.
Restarting the cheat sheet	Any time after starting a cheat sheet, you can restart from the first step by clicking Click to Restart in the Introduction step. If you have already created some artifacts, you will have to manually clean up the workspace before restarting the cheat sheet.
Progressing through the steps	In the current step, when you click Click to Perform, a tool (which can be a wizard), will be launched and you will be required to work with that tool. When you finish working with that tool, the next step is automatically highlighted and it becomes the current step. When the current step is a manual task, you will need to perform the work and click Click to Complete to move to the next step. A checkmark appears in the left margin of each completed step.
Getting help information for tasks	To get step-by-step instructions for that step, click the help link in the step before you click Click to Perform, and the step-by-step instructions on how to work with that tool will be displayed in the Help window. Additional help for entry fields in the tool or wizard may be available by focusing on the field (use the Tab key to position to that entry) and pressing F1.
Skipping a step	If a current step has a Click to Skip option, then it is an optional step. You must click Click to Skip the current step when you do, the step will have the skip mark in the left margin. If the task does not present Click to Skip, you must perform that step and you cannot skip it.
Redoing a step	You can redo any step that you may have completed or skipped in the current cheat sheet. To redo the step, expand the step by clicking its expand icon and then clicking Click to Redo. After redoing a step, the cheat sheet will continue from the redo step.
Closing the cheat sheet	When you finish the last step in a cheat sheet, it automatically restarts. You can also close the active cheat sheet by clicking the close icon in the cheat sheet's toolbar. The active cheat sheet saves its completion status when it is closed so that you can continue where you left off at a later time.

MetaController

The MetaController is a server required by RT-LAB to interact with the RT-LAB simulator. This application runs in the background. The MetaController also helps you to launch all applications related to RT-LAB that interact with the simulator.

Since RT-LAB version 11.x, the MetaController is automatically launched when the RT-LAB user interface is started. Therefore, it is no longer necessary to launch the MetaController before opening the RT-LAB user interface.

System tray icon

On Windows command station, the MetaController is shown in the system tray located in the Windows Taskbar, usually at the bottom right corner next to the clock. See the following figure.

The system tray icon provides various useful features such as starting the RT-LAB user interface. When you right-click on it, a popup menu appears with the available features.

MetaController icon system tray (Windows only)

Menus
Here are descriptions of the MetaController menus:

RT-LAB	Start the RT-LAB Workbench. Double-clicking on the icon in the system tray will also start the RT-LAB user interface.
ScopeView	Starts the ScopeView application to acquire and display signals from real-time simulation. See Using ScopeView for more information.
Help	Opens the RT-LAB Help Center.
Exit	Closes MetaController.

Mouse over

MetaController icon tooltip (Windows only)

When the mouse hovers over the MetaController icon, a tooltip appears to show the current RT-LAB version. It is a good way to know which version is currently used in case of a support request.
