Choose tree is a powerful tmux utility that provides a graphical interface to preview all sessions, windows, and panes, move between them kill them, move them and much more.
The default keybinding
bind-key -T prefix s choose-tree -s
my preferred keybinding to open sessions and windows collapsed and Zoomed in.
bind-key j choose-tree -swZ
From the man page.
choose-tree [-GNrswZ] [-F format] [-f filter] [-K key-format] [-O sort-order] [-t target-pane] [template] 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 follow‐ ing keys may be used in tree mode: Key Function Enter Choose selected item Up Select previous item Down Select next item + Expand selected item - Collapse selected item M-+ Expand all items M-- Collapse all items x Kill selected item X Kill tagged items < Scroll list of previews left > Scroll list of previews right C-s Search by name m Set the marked pane M Clear the marked pane n Repeat last search t Toggle if item is tagged T Tag no items C-t Tag all items : Run a command for each tagged item f Enter a format to filter items H Jump to the starting pane O Change sort field r Reverse sort order v Toggle preview q 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 fil‐ ter 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.
