Ctrl-T considered harmful

Here’s an odd bug in OS X’s Mail.app: if the cursor is either at the beginning or the end of a message you’re composing, and you press the keyboard shortcut for “Transpose characters” (ctrl-T) the application spontaneously quits.

Bummer!

Caution – don’t idly test this out right now if you have an unsaved message open. I know it’s tempting.

MacFixit has a suggested workaround – use ~/Library/DefaultKeyBindings.dict to disable the key – but it’s not ideal since ctrl-T has valid uses in other applications, like invoking spellcheck in Pico or Nano. Unless you tend to hit ctrl-T accidentally, I’d just leave it alone and wait for the inevitable patch from Apple.
