Lets you assign a keyboard shortcut without having to edit a mapping file (ui.xml or uimore.xml) and to restart the Client.
mapKey [modifier-]key command
Where (case not important):
modifier is optional, and its default is no modifier.
mapKey f2 Step mapKey ALT-f2 stepover mapkey Ctl-f2 stepout mapKey ALT-2 run
After you execute the command, the new mapping is reflected immediately in the keyboard. The new mapping does not appear in the mapping file, and it does not remain if the Client is restarted.
