tmux/Mode/Tree

• tmux Tree Mode

  • Tree mode is the hierarchical form of tmux/Mode/Choose. It replaces a pane with a tree of sessions, windows, and panes; each level may be expanded or collapsed.
  • 

  • Entering tree mode

    • tmux/Command/choose-tree enters tree mode directly.
    • tmux/Prefix s runs choose-tree -Zs, opening the tmux/session/Picker with sessions initially collapsed.
    • tmux/Prefix w runs choose-tree -Zw, opening the same mode with windows initially collapsed.
    • choose-session and choose-window are command aliases for choose-tree -s and choose-tree -w.
    • -Z zooms the pane while tree mode is open.
    • With neither -s nor -w, the tree is built all the way down to panes and every branch starts open — choose-tree -Z is the way in when the whole hierarchy should be visible at once.

  • Working in tree mode

    • Navigate and expand the hierarchy, search or filter it, change its tmux/session/Picker/Order, tag items, reorder or kill windows, mark a pane, and toggle the preview.
    • M-+ (tmux/session/Picker/Keyshort/Expand all items) only reaches the depth the tree was built with, so it opens sessions after -s and does nothing at all after -w. Panes come from +, Key/Arrow/Right, or l on a single window — or from entering with choose-tree -Z.
    • Press Enter to choose the selected item and q to return to the starting pane.
    • F1 or C-h opens tmux/session/Picker/Help.
    • tree-mode-preview-format and tree-mode-preview-style configure the preview indicator.
