^+Left Arrow and ^+Right Arrow suddenly stopped working on OS X

I'm not really sure what to make of this. The key combination of ^← and ^→ have stopped working for one of the two users on my OS X installation. I use these keys all the time (switching tabs in terminal, IntelliJ primarily), and it's driving me crazy.

On one user account, it works fine. On the other, it doesn't.

This happened today and nothing significant comes to mind that would have caused some weird keybinding issue.

If anyone has heard of or experienced anything like this, I would very much appreciate your advice!

Thanks.

First, what version of Mac OS X? That's quite important...

For example, my setup is under Snow Leopard (10.6)....

But Check your keyboard settings in system preferences...

• Check Modifier Keys settings, and make sure that your ^ hasn't been remapped...
• Check Keyboard Shortcuts, and make sure that ^+Left ^+Right hasn't been remapped...

Check under Language & Text, and ensure that your home region is set correctly...

These are used in Mission Control. Go to

System Preferences > Keyboard > Shortcuts > Mission Control

And untick or change the keystrokes for Move left a space and Move right a space
