Tmux Prefix Commands – Understanding Two Prefix Commands

tmux

We have a tmux session that several people need to connect to. Some people like the Ctrl+a prefix shortcut and some people prefer the default Ctrl+b shortcut. Is there anything I can put in the .tmux.conf file to allow both shortcuts to work?

It seems that the standard

set -g prefix C-a

command will unset the Ctrl+b shortcut.

I have also tried this:

set -g prefix C-a
set -g prefix C-b

but the second line then unsets the Ctrl+a

Best Answer

For releases prior to 2012: Issue the command only once, with all the desired prefix keys separated by commas:

set-option -g prefix C-a,C-b

For versions >= 1.6 (Released the day before your question, 23/01/2012) see the other answer.
