Panes let you carve a single tmux window into several terminals that share one screen. This category covers splitting a window, moving focus between panes, zooming and resizing them, rearranging their positions, and shuttling panes between windows.

How do I make split panes open in the current directory?
By default tmux opens new panes in the directory the session was started in, not the active pane's directory. Pass -c "#{pane_current_path}" to split-window, or rebind the keys, e.g. bind % split-window -h -c "#{pane_current_path}".
Why does split-window -h split left/right instead of top/bottom?
The -h and -v flags feel inverted: -h creates side-by-side panes (a horizontal row divided by a vertical line) while -v stacks them top/bottom. -v is the default orientation.
How do I type the same command into every pane at once?
Toggle setw synchronize-panes on; while it's active every keystroke is broadcast to all panes in the current window. Run the same command again to turn it off, and remember to — it stays on until you do.
