Terminal CMD + SHIFT + Left/Right Brace No Longer Works

Solution 1:

Edit: Disregard the first part. [ Is the shift of { so we were saying the same thing different ways. I'm leaving this here though regarding disabling the Mission Control shortcuts.

The sequence to cycle forward through tabs is +shift+}, despite what the Window menu says. (+} switches between windows. Very odd.) And +shift+{ cycles backward.

Terminal's Window menu with incorrect keyboard shortcuts displaying for cycling tabs

(You should also be able to reclaim +1, +2, etc. to switch windows in Terminal, which is what the Window menu says those shortcuts do, by going to System Preferences > Keyboard and disabling the keyboard shortcuts that use cmd+ a number under Mission Control. I haven't tested this though.)

System Preferences > Keyboard Preference Pane
