# tmux with the sway desktop's look: a bar on top (workspace numbers, then
# Wren Menu | wifi | vol | bright | bat | timer | date, with the same clicks), black
# and gray, Alt+1 ... Alt+0 for workspaces, Alt+m for the Wren menu. It is
# always installed, so a plain `tmux` after leaving sway looks the same, and the
# console-only extra (extras/console-only.sh) only has to start it at login.
# Inside sway (a foot window) tmux stays plain; the bar and Alt keys (console.conf)
# load only on a text console. The config goes to ~/.config/tmux/tmux.conf; one you wrote yourself is kept
# as tmux.conf.bak.
# Usage: bash console-tmux.sh [--remove]
# status: file:~/.config/tmux/tmux.conf
# files: bin/sway-status bin/console-click bin/console-font data/tmux.conf data/tmux-console.conf data/keys-console.txt
