If your tmux needs are simple (and you're not a Vim person), I think you'll like this one.
It's ripped off from based on Thayer Williams' tmux.conf, so it's clean and elegant.
The 'tick' character is the hotkey. It's underneath your tilde ~ character.
-
tick and + creates a tab. (well, tick and 'equals' = really)
-
tick and - deletes a tab.
-
tick and left/right arrow gets you from tab to tab.
