Is it possible to bind a tmux command to a key combination and use it directly without first pressing the prefix?

I find C-b + n too cumbersome to switch panes, so I was wondering whether I could bind C-1 for example, to switch to pane #1.

Or perhaps there may be a way to make the shortcut in the terminal emulator to send C-b + 1 when I press C-1?

I just use set -g prefix C-a. –  grawity Jan 27 '11 at 20:31
Me too, I just put C-b on my question because that's the default. –  Ivan Jan 27 '11 at 23:05

for your example, use:

bind-key -n C-1 select-pane -t 1

the -n argument to bind-key means no prefix.

Thanks! That almost gets it done, except it doesn't recognize numbers, it says unknown key: C-1. If I use a letter it works. Do you know how I can specify a number key? –  Ivan Feb 3 '11 at 12:36
@Ivan: The usual codes for Control keystrokes come from ASCII. ASCII does not define codes for C-1..C-9. The standard ASCII control characters are C-@, C-a..C-z, C-[, C-\, C-], C-^, C-_, and C-?. Most terminals just do not support distinct codes for most modified keystrokes (though many support some modifiers for arrow keys and functions keys). You are probably better off using F1 in place of C-1 (also note that the pane numbers start at 0, not 1: bind F1 to selecting pane 0, F2 to 1, etc.). –  Chris Johnsen Feb 24 '11 at 5:22
