# ── tmux.conf · kitty as a tmux host ──
# Kitty is a dumb terminal here: tmux owns panes, windows and sessions.
# Every structural chord from kitty.conf is re-sent as a tmux key sequence
# (prefix ctrl+b == byte \x02); an uppercase letter after the prefix byte is
# the shift variant (\x02H == prefix+shift+h).  Actions tmux has no binding
# for run as out-of-band `tmux` client commands (ctrl+shift+g/e/p).
# Launched from the default config with ctrl+shift+t.
