+## mandible-pick
+
+```sh
+mandible-pick
+```
+
+`mandible` (installed with cargo, `~/.cargo/bin`) needs a tool to open, so this asks for one first. fzf lists the executables installed in the `PATH` directories, without shell builtins, keywords, or aliases. <kbd>enter</kbd> opens the highlighted command. If the query contains a space (`git remote add`) or matches nothing, <kbd>enter</kbd> uses it exactly as typed, so mandible opens at that subcommand path. Then it `exec`s `mandible <tool> [subcommand…]`. <kbd>esc</kbd> exits quietly. The command list is built with a bash loop rather than GNU `find -printf`, so it also works on macOS.
+
+**Used by:** the tmux-palette **mandible** item (alias `man`), which runs it in a popup. See [tmux](/terminal/tmux#command-palette).
+
+**Needs:** `mandible`, `fzf` 0.51+ (`--with-shell`, `transform`, `accept-or-print-query`).

 ### Persistence
 
 resurrect saves sessions, windows, panes, cwds, pane contents, and a default set of programs (nvim, less, man, …). Keys: `prefix C-s` saves, `prefix C-r` restores. continuum saves automatically every 10 minutes. When a tmux server starts and no other tmux server is running, continuum restores the last save. In practice that means the first Ghostty window after login or a reboot.
