In cases like these, where you KNOW what command you want with such a  
key, best is to trigger actions like this:

var_SetInteger( p_intf->p_libvlc, "key-action", ACTIONID_PLAY_PAUSE );

This triggers code in hotkeys.c (key-action differs from key-pressed,  
in that it is agnostic of the key used, it only cares about the action  
that needs to be triggered)
