Recently, I've realized that my ^A key binding has stopped working in OSX.

My assumption is that some application has registered ^A as a hotkey, but I don't know that for certain. I don't recall installing anything new lately, but it's certainly possible that I did and just forgot.

Some other pertinent info:

  • ^A doesn't work in any application -- this isn't just a issue
  • Other control combos (eg: ^E) still work as expected
  • Looking through the Keyboard System Preferences pane shows nothing bound to ^A
  • A reboot doesn't help
    • However, logging into under a freshly made account does cause the issue to go away (i.e.: ^A works for the test account)
  • My StandardKeyBinding.dict has the correct value for ^A
    • Note: I don't have a DefaultKeyBinding.dict in /Library/KeyBindings or ~/Library/KeyBindings

Any ideas on how to debug this?

Thanks, I did that. – nall Jun 22 '11 at 22:38

I'd still like comments on how to debug this kind of thing in general, but the answer to this point problem is answered here:

You can fix this problem by deleting the following plist file, which will reset all your keyboard shortcuts: in ~/Library/Preferences, and then logging out and back in again.
