http://superuser.com/questions/52483/terminal-tips-and-trick... doesn't work for me; it seems I can hold ESC for arbitrarily long without evoking Terminal's interest. I'm using the Vi keymappings (set -o vi), so I guess that's no surprise; but is there a Vi equivalent?
Ah, silly me. Somehow I read “only built-ins” instead of “including built-ins”, and so thought that it was something more than (or at least different from) ordinary tab-completion.
