When I was using Alfred 1.x I could set command+options+/ as the hotkey to open. But I found I can't change default opening hotkey into this like before in latest version as 2.8.3. I have searched the forum for this issue but haven't found anything related. And I am using 10.11. I also had a try on my friend's OS X 10.11, it can't be done either. Hope you can help.
