Command-Left/Right Arrow not working

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.

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.
