Keyboard shortcut for switching panes in tmux in iTerm2 on OS X

Question

I have tmux installed with iTerm2 on OS X.

While I can do Cmd+left/right to switch between tabs, I cannot seem to be able to switch between panes under the same tab using Ctl+b o (that is, Control and b together, followed by an o?) as suggested by others.

I don't think I've touched any default key binding for tmux, so what is the correct keyboard shortcut for this operation?

Solution

Cmd + Opt + Up or Down or Left or Right works for me.

Ctl+b doesn't invoke tmux commands in iterm2, at least not mine.

Control-b is the default prefix in tmux, unless you change it in your configuration. I don't know exactly how iTerm 2's tmux integration works, having never really felt better than just using tmux directly.
