Very strange behavior I'm seeing today.
My left/right arrow keys work. Even Option-Left/Right works correctly.
But, Command-Left-Right do not work. No movement at all.
Curiously, Shift-Command-Left/Right work fine.
I've not changed any keyboard shortcuts recently. I've checked the keyboard shortcuts that are currently defined. Nothing that would indicate a problem, but clearly there is.
MacBook Pro, Mac OS X (10.7.2)
Just found a solution that worked for me here. Basically, it seems to be a bug with the Dock. If you type "killall Dock" (the command is case-sensitive) into the command line in Terminal, it restarts the Dock. After that the arrows seem to work normally again.
The exact same thing just happened to me. Last night command-right-arrow and command-left-arrow allowed me to move multiple columns in Excel, and now they don't. I haven't knowingly changed any settings, and as far as I can tell those commands aren't in use by any system progrma. Command-up-arrow and command-down-arrow still work normally. If anyone can tell me what happened and how to fix it I would be very happy—this is really frustrating.
for me it was the same situation (CMD+Left/Right didn't work) but the solution was another...
if you have installed HEAR (system wide equalizer) close this window. then the commands will also work again.
The "killall Dock" in terminal worked for me!
This totally helped me.. thanks!
> killall Dock
Worked great! Thanks!
Confirmed @ OS X 10.7.5
Thank you! Also solved for me!
killall Dock worked! Thanks
Command-Left/Right Arrow not working
