Change the tmux prefix to ctrl+space
April 1, 2020 ‐ 1 min read
Tmux uses ctrl+b as default prefix. I rather have it set to ctrl+Space. The space bar is hard to miss. And I use it as leader in VIM, so I like the consistency.
To configure the prefix we need to make a change in the ~/.tmux.conf file. Following the example in the tmux man pages, we make the following addition in the tmux config.
# ~/.tmux.conf
unbind-key C-b
set-option -g prefix C-Space
bind-key C-Space send-prefix
