Multiple hotkeys for same action

[traycer]

I'd like to assign more than one hotkey to the same action, e.g.: bind the faster/slower playback actions to PageUp/PageDn, Alt-MouseUp/Alt-MouseDn, and Keypad+/Keypad-. I can currently workaround this using something like AHK, but it would be much preferable with this functionality in VLC itself. Thanks.
