Button Header

The Floating Buttons displayed in the top middle of the work area allow the user to complete diagram actions quickly and easily. Hovering on each of the buttons explains the action each button does (tool tips), and when a button is displayed in a lighter blue, it means the task cannot be done in the current context.

The following actions can be performed, from left to right:

	Undo	Undoes an action just performed on the diagram, whether it is an addition of a new block, moving, deleting, rotating or editing a parameter.
	Redo	After an undo, this redoes the action, setting the block back to its previous state.
	Delete	This deletes the selected block(s).
	Cut	This action copies and removes the selected block(s).
	Copy	This action copies the selected block(s).
	Paste	This action pastes the selected block(s).
	Duplicate	This action copies and pastes the selected block(s).
	Hide/Show Label	This button toggles the viability of the label(s) of the selected block(s).
	Rotate Counterclockwise	This action rotates the block(s) 90 degrees backward (counter-clockwise), as shown on the icon of the button.
	Rotate Clockwise	This action rotates the block(s) 90 degrees forwards (clockwise), as shown on the icon of the button.
