iterm2macostmux
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?
You want to invoke a sequence of keystrokes (first Ctrl-b, then n ranging from 0 to 9).
Your best bet is to use a keyboard shortcut utility such as Butler or Keyboard Maestro to do this for you.
Using Butler:
Select + » Smart Item » Keystrokes, configure the hotkey Cmd-1. Press Ctrl-B, then 1 for the Keystrokes. Configure it to be only valid in Terminal (or iTerm). It will warn you that other applications might not like it, but you know that already.
Using Keyboard Maestro:
Create a new group on the left that is only available in Terminal (or iTerm).
Add a new item, triggered by Hot Key Trigger (Cmd-1) and add two Keystrokes to its actions: Ctrl-B and 1.
You might also want to take a look at this topic -- doesn't use Command though, and didn't work for me using Terminal.
From the tmux documentation:
Bind key key to command. Keys may be specified prefixed with ‘C-’ or ‘ˆ’ for ctrl keys, or ‘M-’ for alt (meta) keys. The −r flag indicates this key may repeat, see the repeat-time option.
They don't support a third modifier key.
I tried putting together a cheat sheet or reference card. After exploring various possibilities I ended up doing the following:
TL;DR - stick to using prefixes where available, e.g. ctrl+a in tmux, ctrl+o (Dvorak)/ctrl+s (QWERTY) in vim and irssi. This seems to have the least consequences and be somewhat cross-platform-friendly.

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