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. |
