# menu, in a floating, centered window (bin/wren-menu), named by what you want
# to do: browse, chat, files, notes, passwords, More apps, Wi-Fi, Privacy,
# Settings, Is my computer OK?, Help (the key cheat sheet), About this computer
# and Lock, sleep, shut down. Arrow keys and Enter choose, or
# click; Esc goes back from a list, and closes the rest. What you choose runs in
# that same window. Super+? still opens the cheat sheet straight away.
# Also the Wren Linux command (wrenctl --help, --update, --apps, wrenctl install
# NAME...), its man page and its Tab completion, so the same things are one
# word away in a terminal.
