In tmux you can switch to window 2 with prefix_key + 2. I'd like to press rather prefix_key + u.

I tried in .tmux.conf this:

bind-key u 2

and this:

bind-key u select-window -t 2

Which doesn't work. Is it possible to create such mapping?

You need to include a colon to select based on index. Try this:

bind-key u select-window -t :2

This doesn't help. – xralf May 12 '12 at 13:10
Did you reload your .tmux.conf? Also keep in mind window index are zero based unless you change with: set-option -g base-index 1 – pengwynn May 12 '12 at 13:17
I exited tmux and lxterminal several times. I know it's zero based. – xralf May 12 '12 at 13:24
tmux instances share the same tmux session, _.tmux.conf is only read when the session is started. Make sure that the tmux list-sessions list is empty, or explicitly run source-file ~/.tmux.conf after starting tmux. – Thor May 12 '12 at 13:52
@Thor Thanks a lot. source-file was necessary. – xralf May 12 '12 at 17:12
