commit 899aaa97827f263c877faab3f8d0686fd9784b66

    Simplify computing of shortcut name in the dialog.
    
    Instead of handling the key-pressed event with XKB code, we now use
    gdk/gtk functions directly which simplifies things a lot.
    
    This needs testing to ensure that there is no regression and that
    shortcuts with Numlock work.
