# - prefix + X - kill current session without detaching tmux.
# - prefix + S - switches to the last session.
#                The same as built-in prefix + L that everyone seems to override with some other binding.
# - prefix + @ - promote current pane into a new session.
#                Analogous to how prefix + ! breaks current pane to a new window.
