I had a similar idea while adding more features to my mythbrowser 
module. I just didn't have enough buttons to map all the features I 
wanted to the keyboard. I thus came to the conclusion that some kind of 
popup menu is needed.

I thus like Tako's idea very much but I would go even a step further:

Here comes my vision of a myth popup menu:

- Menuitems should not only be limited to Labels/Images but it should
   also be possible the e.g. change their value with the left/right
   buttons. In particular I thought of

     + binary option with a checkmark
     + value options such as volume/brightness/color/zoom-level...

   this way we would for example control the livetv settings without all
   the F-keys from a simple menu!

- Here comes the real nice part! It should be possible to map each menu
   items left/right actions to a key via a text config file. The user can
   therefore map e.g. the volume control to two keys of his choice on the
   keyboard and therefore define some kind of a short-cut to the menu. If
   one could subsequently hide such a keyboard-mapped option from the
   popup menu would of course be nice too.

If all myth keyboard actions are defined in such a popup menu, that can 
tailer it to his needs and to suit his remote. It should even be 
possible to control myth with only the cursor keys, a menu key and the 
activation key.

I posted the same text on a new thread called 'MythPopupMenu' because I 
think the issue is to important to be burried in a deeply nested thread.
