How to assign multiple hotkeys to the same action?

Here're my current hotkeys:

Given this config, I'm losing Space for pausing/playing, so the question is, how to bind Space and K (multiple hotkeys) to "Play / Pause"(same action)?

I don't think there is a way to do this with VLC alone, however, you could use autohotkey on Windows platforms to implement this functionality yourself.

A script like this might be useful to press the 'k' key whenever space is pressed but only when VLC is focused:

#IfWinActive ahk_exe vlc.exe

Space::send, {k}
  
#IfWinActive
