tmux keybinding reference

Sourced directly from this platform's own /etc/tmux.conf, not the stock tmux defaults. The prefix is Ctrl-a everywhere below unless a row says otherwise.

Key	Action
`Ctrl-a`	Prefix key (replaces the default `Ctrl-b`).
`prefix` `\|`	Split the window vertically, new pane opens in the current pane's directory.
`prefix` `-`	Split the window horizontally, same current-directory behavior.
`prefix` `h` / `j` / `k` / `l`	Move to the pane left / below / above / right (vi-style).
`Alt+←` / `→` / `↑` / `↓`	Move between panes with no prefix at all.
`prefix` `H` / `J` / `K` / `L`	Resize the current pane 5 cells at a time (repeatable, hold to keep resizing).
`Alt+1` ... `Alt+9`, `Alt+0`	Jump straight to window 1-9, or 10, no prefix.
`Alt+f`	Jump to the last-used window, no prefix.
`Alt+n` / `Alt+p`	Next / previous window, no prefix.
`prefix` `[`	Enter copy mode (vi keys inside).
`v` (in copy mode)	Begin a selection.
`y` (in copy mode)	Copy the selection and exit copy mode, straight to the system clipboard via `tmux-yank` and OSC 52.
`r` (in copy mode)	Toggle rectangle (block) selection.
`prefix` `r`	Respawn a fresh shell in the current pane after a crash (see the always-on section for why this matters).
`prefix` `R`	Reload `/etc/tmux.conf` without restarting the server.
`prefix` `Z`	Pop the current pane fullscreen in a popup (power-zoom).
`prefix` `f`	Open `rzf`, a fast terminal file explorer, in a popup rooted at the current pane's directory. Deliberately not a bare `Ctrl-f`, which would collide with readline and vim's own bindings.
Mouse	Click to select a pane, drag to resize, scroll wheel to scroll, drag to select text for copy.

Always current, straight from the running config: tmux list-keys.
