# tmux choose-tree Source: https://libtmux.org/en/tmux/3.2a/manual/choose-tree/ > Put a pane into tree mode, where a session, window or pane may be chosen interactively from a tree. Put a pane into tree mode, where a session, window or pane may be chosen interactively from a tree. ## Syntax ```tmux-usage tmux choose-tree [-GNrswZ] [-F format] [-f filter] [-K key-format] [-O sort-order] [-t target-pane] [template] ``` ## Behavior Put a pane into tree mode, where a session, window or pane may be chosen interactively from a tree. Each session, window or pane is shown on one line. A shortcut key is shown on the left in brackets allowing for immediate choice, or the tree may be navigated and an item chosen or otherwise manipulated using the keys below. `-s` starts with sessions collapsed and `-w` with windows collapsed. `-Z` zooms the pane. The following keys may be used in tree mode: | | | | ---------------------------------------------------------------- | ------------------------------------------------------------------------ | | [**Key**](https://libtmux.org/en/tmux/3.2a/manual/full/#Key~2) | [**Function**](https://libtmux.org/en/tmux/3.2a/manual/full/#Function~2) | | [`Enter`](https://libtmux.org/en/tmux/3.2a/manual/full/#Enter~2) | Choose selected item | | [`Up`](https://libtmux.org/en/tmux/3.2a/manual/full/#Up~2) | Select previous item | | [`Down`](https://libtmux.org/en/tmux/3.2a/manual/full/#Down~2) | Select next item | | [`+`](https://libtmux.org/en/tmux/3.2a/manual/full/#+) | Expand selected item | | `-` | Collapse selected item | | [`M-+`](https://libtmux.org/en/tmux/3.2a/manual/full/#M-+) | Expand all items | | [`M--`](https://libtmux.org/en/tmux/3.2a/manual/full/#M--) | Collapse all items | | [`x`](https://libtmux.org/en/tmux/3.2a/manual/full/#x~2) | Kill selected item | | [`X`](https://libtmux.org/en/tmux/3.2a/manual/full/#X~2) | Kill tagged items | | [`<`](https://libtmux.org/en/tmux/3.2a/manual/full/#_) | Scroll list of previews left | | [`>`](https://libtmux.org/en/tmux/3.2a/manual/full/#_~2) | Scroll list of previews right | | [`C-s`](https://libtmux.org/en/tmux/3.2a/manual/full/#C-s~2) | Search by name | | [`m`](https://libtmux.org/en/tmux/3.2a/manual/full/#m) | Set the marked pane | | [`M`](https://libtmux.org/en/tmux/3.2a/manual/full/#M) | Clear the marked pane | | [`n`](https://libtmux.org/en/tmux/3.2a/manual/full/#n~2) | Repeat last search | | [`t`](https://libtmux.org/en/tmux/3.2a/manual/full/#t~2) | Toggle if item is tagged | | [`T`](https://libtmux.org/en/tmux/3.2a/manual/full/#T~3) | Tag no items | | [`C-t`](https://libtmux.org/en/tmux/3.2a/manual/full/#C-t~2) | Tag all items | | [`:`](https://libtmux.org/en/tmux/3.2a/manual/full/#:) | Run a command for each tagged item | | [`f`](https://libtmux.org/en/tmux/3.2a/manual/full/#f~3) | Enter a format to filter items | | [`H`](https://libtmux.org/en/tmux/3.2a/manual/full/#H) | Jump to the starting pane | | [`O`](https://libtmux.org/en/tmux/3.2a/manual/full/#O~2) | Change sort field | | [`r`](https://libtmux.org/en/tmux/3.2a/manual/full/#r~2) | Reverse sort order | | [`v`](https://libtmux.org/en/tmux/3.2a/manual/full/#v~3) | Toggle preview | | [`q`](https://libtmux.org/en/tmux/3.2a/manual/full/#q~2) | Exit mode | After a session, window or pane is chosen, ‘`%%`’ is replaced by the target in `template` and the result executed as a command. If `template` is not given, "switch-client -t '%%'" is used. `-O` specifies the initial sort field: one of ‘`index`’, ‘`name`’, or ‘`time`’. `-r` reverses the sort order. `-f` specifies an initial filter: the filter is a format - if it evaluates to zero, the item in the list is not shown, otherwise it is shown. If a filter would lead to an empty list, it is ignored. `-F` specifies the format for each item in the tree and `-K` a format for each shortcut key; both are evaluated once for each line. `-N` starts without the preview. `-G` includes all sessions in any session groups in the tree rather than only the first. This command works only if at least one client is attached. ## C implementation Internal declarations in tmux 3.2a: * [`cmd_choose_tree_entry`](https://libtmux.org/en/tmux/3.2a/reference/c-variable-cmd_choose_tree_entry/) * [`cmd_choose_tree_exec`](https://libtmux.org/en/tmux/3.2a/reference/c-function-cmd-choose-tree-c-cmd_choose_tree_exec/) ## Use from a library Each API describes its own defaults, errors and execution model. * [Python](https://libtmux.org/en/py/latest/reference/libtmux-pane-choose_tree/) * [TypeScript](https://libtmux.org/en/ts/latest/reference/pane-pane-choosetree/) * [Go](https://libtmux.org/en/go/latest/reference/tmux-pane-choosetree/) * [C#](https://libtmux.org/en/csharp/latest/reference/libtmux-pane-choosetreeasync/) tmux sources and license Syntax comes from `tmux 3.2a list-commands`.
