This command sends <anything you want> in such a way that it can be caught by ON HOOK "anything you want" or any regular ON syntax. E.g. if you have ON HOOK * echo one $* three and you send HOOK two it will display "one two three" as the on is activated. This is useful if you want to put a special hook in a script or alias that you can act upon with an on/hook or ignore at will.
