This command will cancel:
¨ Inside a tool: the last operation done with the tool.
In this case, there will be as many cancellations possible as operations previously done within the tool.
¨ No tool selected: all the operations done with the last tool used.
In this case, the number of cancellations (undo) possible is user-defined in the “Edit/Preferences” menu. (See chapter Edit/Preferences/Recovery/Number of undos.)
You can also use the Undo icon button of the Assistant Palette to cancel an action. (See chapter User Manual/Tools/Assistant Palette.)
