Some reminders:

Leaving and entering tmux

tmux => creates a new tmux session
tmux ls => lists active tmux sessions
tmux a -t target-session => reattach to the target-session
tmux a => reattach to the most recently used unattached session

CTRL-A + D => within a tmux session, deattaches from it, leaving it running (type tmux a to reattach to it)

Windows

CTRL-A + C => creates a new window
CTRL-A + [0-9] => changes to window [0-9]
CTRL-A + W => changes to the last active window (flagged with a - after the window name in the status bar)
CTRL-A + , => allows to rename the active window

Panes

CTRL-A + _ => splits the active pane horizontally
CTRL-A + | => splits the active pane vertically
CTRL-A + CTRL-A => changes to the next pane in the same window (in a circular way)

CTRL-A + : + break-pane => extracts the active pane to a new window

CTRL-A + cursor keys => increases the size of the active pane in the direction of the cursor key

CTRL-A + Z => zoom to the active pane (i.e. go full-window). CTRL-A + Z to zoom out back to the original window layout

c'est comme ma toyota.
fantastique.
