Config & Misc

# Reload the configuration without restarting tmux
tmux source-file ~/.tmux.conf

• The user configuration file lives at ~/.tmux.conf.
• The prefix key (default C-b) precedes every in-tmux keybinding; it can be remapped in ~/.tmux.conf (e.g. to C-a).

Notes

• C-b means hold Ctrl and press b; release, then press the command key.
• The default prefix is C-b; many users remap it to C-a in ~/.tmux.conf for easier reach.
• CLI commands (tmux new, tmux ls, etc.) run from the shell; keybindings like C-b d run from inside a tmux session.
• See the tmux wiki for the full command and keybinding reference.
