Description of the new feature/enhancement

It would be nice to have an option to trigger MenuComplete on a consecutive tab press like Zsh's AUTO_MENU. Basically first and second tab act like Complete/Bash does, but pressing it again while the list of options is shown switches to menu completion.

Proposed technical implementation details (optional)

A new function that can be bound to tab that acts this way? Or a config parameter to switch Complete to behave that way.
