How to enable CTRL+4/5/6?
Solution 1:
I had a similar issue of unresponsive Ctrl+3 and Ctrl+4 keystrokes using OS X 10.8.4 and found a solution that worked for me using information from this answer.
- Open
~/Library/Preferences/com.apple.symbolichotkeys.plist
(I used XCode). - Update keys for the shortcuts which are giving you trouble by switching
enabled
toNO
. I switched120
and121
, which represent Ctrl+3 and Ctrl+4. I am not sure about Ctrl+5 or Ctrl+6. - Restart your computer.
Hope this helps!
