How to disable Command+Shift+R? I have been using command+shift+R in Sublime Text forever (super+shift+R in Sublime). On my iMac all that happens is that I hear a beep (on Sierra).

It is really annoying and I can't find a way to remove the shortcut or remap it. Anything I've tried so far hasn't yielded any results.

Karabiner isn't working in Sierra and I tried some other app BetterTouchTool that doesn't seem to help either.

Is there a way to force my Mac to unbind that shortcut?
A beep indicates that the shortcut that was pressed was not interpreted by apps on the system. This means the shortcut is already unbound, so it seems you're having some problem with Sublime Text itself rather than the shortcut being bound to something else.
