Command Right/Left stopped working

I found s solution, so I'll leave it here for anyone who's having my same issue.

I had swapped Command and Control and under System Settings > Keyboard > Shortcuts > Mission Control the shortcut Control+Left and Control+Right were being used by mission control. I unchecked those two shortcuts (because I don't use Mission Control), but changing them to something else would do the trick as well.

I recently played with the Mission Control keys and assigned desktop moving keys to shift+command+arrow, which caused the issue.

Switching the keys to Alt+arrow didn't help, since the keys got un-assigned from somewhere else the keyboar shortcuts don't show.

What worked for me was to reset shortcuts and re-assign my mission shortcuts straight to alt+arrow.

I have this exact problem. Very interested in a solution other than rebooting or logging out/in.

New information: killing the Dock is enough to eliminate the problem. So it's a malfunction of the Dock that causes this.

In the Terminal.app, just:

killall Dock

It will relaunch and your command-arrow keys will work again.

No, `killall Dock` does not work in my case. All of the other bindings such as contro-a/e, etc. seem to be working as per normal.

Thank you!

This worked for me! Thank you so much! I would have never thought of anything like that.

I tried the killall Dock and the dock refreshed but I still am not getting the Command Shift arrow to work.

I just upgraded to the Office 2016.

Hello!

The "killall Dock" solution doesn't work with me. Do you have any other recommendation?

Thanks!
