Some news things:

 . I am still going on modifiying the key event handling method to make it more flexible. I still have a few things to get what I'd like to
 . added a keystrokes.h include which contains a generic name of all the VLC keys binding
 . modified some of the core interface routines to allow the passing of an extra parameter with a keystroke (VLC_CHANNEL).
 . next step: move all the interface dependent parts (such as the getKey function) to the plugins.

Hope this will run on your boxes...
