tmux/Q/How can I turn mouse mode on using a keyboard shortcut?

• How can I turn mouse mode on using a keyboard shortcut in tmux?

  • AI Answer

    • Short answer: Stock tmux has no dedicated mouse key. Open the tmux/Command/Prompt with tmux/Prefix : and run set -g mouse on. Review card: tmux/Keyshort/Enable Mouse.

    • Steps

      • 1. <prefix> : (e.g. Ctrl-b then :)
      • 2. Type set -g mouse on → Enter
      • Off: set -g mouse off. Query: show -gv mouse.
      • Runtime-only — gone after tmux kill-server. Same pattern as tmux/Cheat Sheet.

    • Optional: bind a toggle in your config

      • tmux

        bind m set -g mouse \; display-message 'Mouse: #{?mouse,ON,OFF}'

      • Then <prefix> m toggles. Reload with <prefix> : → source-file ~/.tmux.conf.
