Toggle pane zoom
panes
// what it does
Ctrl+b z toggles zoom (resize-pane -Z), temporarily expanding the active pane to fill the entire window and hiding the others. Press it again to restore the previous layout exactly. Useful for reading long output or focusing on one pane without permanently changing your splits.

Ctrl + bz
// gotcha
The other panes are hidden, not closed — a Z appears in the window's status flags to remind you. Many pane operations (splitting, selecting another pane) silently unzoom, so the zoom state is easy to lose.
