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!
