I just upgraded to Mountain Lion and I'm perplexed to find that neither iTerm 2 or the standard terminal will not receive Control ⌃+ or +, which I typically use to jump words on the command line. I can, however, use + and + which I'm finding odd.

I've tested this by opening up cat on stdin and mashing buttons. My initial guess is that OS X is intercepting them somehow, I suspected Spaces (I guess it's part of Mission Control now) at first, but after disabling all key combinations for it, I've come up empty-handed.

Has anyone ever seen this before, or does anyone have any other ideas?

This is because ctrl+ and ctrl+ are bound to changing spaces in Mission Control.

Keyboard Shortcuts

The OP's question indicates that he's removed those shortcuts. – Jason Salaz Sep 5 '12 at 1:32

optionf - Jump Forward a Word

optionb - Jump Back a Word

From the bash manpage:

   forward-word (M-f)
         Move forward to the end of the next word.  Words are composed of alphanumeric characters (letters and digits).
  backward-word (M-b)
         Move back to the start of the current or previous word.  Words are composed of alphanumeric characters (letters and digits).

If you open up (the OS X built-in terminal), open preferences, choose the 'Settings' section, and click 'Keyboard' in the navigation strip.

Terminal Keyboard Preferences

The shortcut is defined here. It may be possible to modify that, or I would suggest duplicating it, using control cursor left with the same \033b action, and control cursor right with \033f.

This doesn't help that the terminal won't respond to ^← or ^→. I know how to bind keys to actions, but I don't know why the terminal isn't responding to the keys being pressed. – jordanstephens Sep 4 '12 at 21:52
I think you should file a Radar that even when you disable the shortcut, something still traps it. – Jason Salaz Sep 5 '12 at 1:34
I can verify that Terminal will respond to Control-Left/Right if they aren't intercepted elsewhere. The default Terminal keyboard map even includes mappings for them, and they work if I turn off the Mission Control shortcuts. – Chris Page Jan 16 '13 at 14:08
