Once the New Account setup wizard has been started on first run via a simple invocation
aerc, there appears to be no way to quit / sigterm the wizard. The typical Shift+: interface is unavailable, Ctrl+c (standard sigterm) does not register, and the Escape key does not do anything noticeable. Even adding a "Quit" option to the tabbed menu would be better than the current arrangement of getting trapped. I believe this will improve the setup wizard for anyone wishing to back out or demo the wizard. Good work.
