libtmux:move-pane

Move SOURCE pane beside DESTINATION; return an outcome with the moved pane. DIRECTION is :HORIZONTAL or :VERTICAL. SIZE is cells; PERCENT is 1..100, mutually exclusive with SIZE. BEFORE changes placement and FULL-SIZE spans the window. Percent sizing retains tmux's version semantics: with FULL-SIZE, 3.3a uses destination-pane dimensions and 3.8 uses whole-window dimensions. Use SIZE for cell-based control. DETACHED defaults true. An emptied source window is destroyed, including all its links. With DETACHED false, tmux chooses the session context of the physical destination. OBSERVE supplies a replacement source pane; its old observation retains its old window. Signals STALE-TARGET or an operational condition.
