Ability to turn off all sytem-wide hotkeys

I must misunderstood your answer then:

So I think that requesting for that has no sense.

Good that it will be possible.
+1 for option to disable/enable global hotkeys.

And small request - if is possible - maybe in customize mode I can check some additional checkbox like "do not disable" - so I can choose which ones global keys will be still active even if I disable global keys by button.
