Making tmux Pretty and Usable (2024)

Just editing ~/.tmux.conf can greatly improve tmux's usability.

• Change the prefix key from the default C-b to the easier-to-use C-a, while keeping the original behavior with C-a C-a.
• Rearrange pane split keys from " and % to | and - to match their meaning and behavior.
• If you change your config often, bind source-file ~/.tmux.conf to r so you can reload instantly.
• Use Alt + arrow keys to move between panes without the prefix, speeding up navigation.
• Turn on mouse mode to enable clicking to select windows/panes and resize panes.
• Use allow-rename off to disable automatic window renaming, so manually assigned names persist.

On the appearance side, set styles for the status bar, pane border, copy mode, and messages individually to create a consistent theme.

• To preserve your terminal's default colors, use named colors like red and yellow,
• and if you need finer control, you can use 256-color values like the colour0 series.

Finally, it suggests that if you want to dig deeper, refer to the tmux man page, the tmux wiki, and other people's tmux.conf or dotfiles.
