Then you should probably set up Window Manager/Desktop Environment key 
bindings.

MythTV has key bindings which map keys to MythTV actions and jump points 
which, basically, allow you to jump to a specific location in MythTV.

There is no support for running random scripts in response to keys (and, 
I don't think there's need for such with irexec and WM's/DE's already 
providing such support).  The only real benefit of allowing it would be 
that mythfrontend could set itself to ignore LIRC messages until the 
script/application finished executing, but better would be to add a 
generic approach for a script or application to tell mythfrontend to 
ignore LIRC messages until told to resume LIRC processing.  That way, 
the "ignore LIRC for a bit" functionality could be used with scripts 
that are triggered via irexec or key bindings or command prompt or ...
