Completion Options

always_last_prompt

• if zsh prints out a list (eg. on an ambiguous completion), it reuses the old prompt instead of printing a new one underneath the list; this breaks menucompletion if turned off

complete_aliases

• don't expand aliases _before_ completion has finished

complete_in_word

• if unset the cursor is set to the end of the word if completion is started

list_ambiguous

• complete as much of a completion until it gets ambiguous.

glob_complete

• cycle through globbing matches like menu_complete

rec_exact

• in completion, recognize exact matches even if they are ambiguous.
