> You mean "System go to layout"?
Could you give more information as to what you are trying to do, for "restart layout" restarts the current layout and is basically the same as " system go to layout" only referencing the current one as opposed to another one..
From the manual:
Restart the current layout. Note that unlike Go to layout, this action resets all event groups to their initial activation state. Global variables keep their current value - they are not reset. To reset them use the system action Reset global variables.
