Do Mapped Key Action
The Target of a Do Mapped Key Action indicates which windows will effectively press the Mapped Key's Hotkey, activating the Mapped Key from that particular window. If the Target includes multiple windows, all of those windows will perform the Mapped Key as instructed. Also note that this does not affect the Targets of any Action in the Mapped Key, so take care to select the right Target.
Do Mapped Key Action supports Round-robin via a check box. When activated, the Mapped Key will be performed by one window matching the Target at a time.
The Description box at the bottom of this Action shows the Mapped Key's Description. This can be useful in reminding you to use the right Target, or providing other helpful information.
