Have keypad/numpad shortcuts appear correctly in dialog
In Xubuntu 20.04, window tiling is assigned to Super + Keypad [1..9], but appear in the dialog as Super + [1..9], which is confusing as Super + [1..4] are assigned in the Keyboard preferences dialog for various apps.
I propose that KP_[1..9] appear as 'Keypad [1..9]'.
