tmux/Q/How can I find all keyshorts including custom keybindings?

• How can I find a more complete list of the default Keyshorts for tmux from the CLI? card

  • My Answer

    • use C-b ? to see some of the
      • This list doesn’t show any of the custom keybindings you create
    • to see all keyshorts, use tmux/list-keys
      • My favorite way - at the CLI, pipe list-keys into bat
        • tmux list-keys | bat
      • For interactive browsing, pipe through fzf with a bat preview
        • tmux list-keys | fzf --preview 'echo {} | bat -l sh -p --color=always'
        • fzf/--preview runs a command on each candidate and shows output in a side pane
        • bat/--language (-l sh) forces shell syntax highlighting
        • bat/--style (-p) removes UI chrome (no header, line numbers, or borders)
        • bat/--color (--color=always) keeps syntax colors even in a subprocess (bat strips them when stdout is not a TTY)
      • inside of tmux
        • open the tmux/Command/Prompt with tmux/Prefix :
          • enter list-keys
          • hit Enter to get out
    • My Notes
      • at first I was confused by this suggestion, because there's a lot of noise from long commands, but really they are there.

    • Short answer: the full list lives in tmux list-keys, which dumps every key table (~267 bindings on a default 3.6a). C-b ? only shows one table.
    • What C-b ? actually shows: prefix ? runs list-keys -N, which prints the prefix key table only (bindings reached after the prefix). On tmux 3.6 every prefix binding carries a note, so ? already shows all ~87 of them — it is complete for the prefix table.
    • Why it still feels incomplete: -N omits the other key tables entirely. root (mouse events and -n chords), copy-mode, and copy-mode-vi carry no notes, so nothing from them ever appears in C-b ?. That hides ~180 bindings — e.g. bind-key -T copy-mode-vi v send-keys -X rectangle-toggle.
    • Commands that show everything:
      • tmux list-keys — every binding across all tables, printed as bind-key lines exactly as in a .tmux.conf. Verbose by design; that density is the completeness.
      • tmux list-keys -T prefix — just the prefix table (the same set C-b ? shows).
      • tmux list-keys -T copy-mode-vi — copy-mode bindings for vi keys (use copy-mode for emacs keys).
      • tmux list-keys -T root — prefixless bindings (mouse, and chords bound with -n).
      • tmux list-keys -N — only noted bindings; on 3.6 this equals the prefix table.
    • Gotcha — table names: the tables are prefix, root, copy-mode, and copy-mode-vi. There is no C-b table, so tmux list-keys -T C-b errors with table C-b doesn't exist. The prefix key (C-b) is printed on each line, but the table itself is named prefix.
    • Interactive per-key lookup: prefix / prompts you to press a key, then shows that binding (it is bound to command-prompt -k -p key { list-keys -1N "%%" }).
    • Offline manual: man tmux only works when the man page is on MANPATH. A mise-managed tmux ships no man dir under its install, so man tmux returns No manual entry for tmux. Read it online at man.openbsd.org/tmux.1, or point man straight at the file (man /path/to/tmux.1.gz).
    • Grep for one binding: tmux list-keys | grep split-window finds which keys run a command (across all tables); add -T prefix to scope the search to one table.
