global hotkeys - mute, etc

Im playing with the ctrl m, and while I think it will work in a pinch, it's likely not exactly what the user will be looking for.

If I use ctrl-m in the chrome browser, it mutes me perfectly.
But my users will be using two chrome windows, and may not have OBSN in the foreground at that moment. When not in the foreground, CTRL-M has no effect.
I tried it with the electron app, which has different results: when you push ctrl-m, it mutes your mic and minimizes the electron window.
The same issue comes about as soon as the electron app is not in focus - doesnt mute (or minimize).

I'll have to think on this, it may be a behaviour I have to change on my user's end.
