Cheat sheet

Browse in tree mode

Goal

Attached to deploy by tree, then to build with window output current.

Two keys open the same tree at different depths:

C-b s
sessions
C-b w
sessions with their windows shown

Inside, no prefix is needed:

Up / Down
move
Right / Left
expand or collapse
Enter
choose
q
leave

The top half is the tree, the bottom a preview of the selected item’s panes. What you choose decides where you land: a session line attaches you to whichever window it already had current, while a window line makes that window current and attaches you there.

Do this

Press C-b s, then Down twice to deploy, then Enter.

The status line reads [deploy].

Press C-b w, move to output under build, then Enter.

Every session shows its windows; the status line now reads [build] with output current.

Tree mode is a temporary mode

Tree mode is one of tmux’s modes, like the view mode behind C-b ?: the pane’s keys are borrowed until you leave.
