Function: choose-completion

choose-completion is an interactive and byte-compiled function defined in simple.el.gz.

Signature

(choose-completion &optional EVENT NO-EXIT NO-QUIT)

Documentation

Choose the completion at point.

If EVENT, use EVENT's position to determine the starting position. With prefix argument NO-EXIT, insert the completion at point to the minibuffer, but don't exit the minibuffer. When the prefix argument is not provided, then whether to exit the minibuffer depends on the value of completion-no-auto-exit. If NO-QUIT is non-nil, insert the completion at point to the minibuffer, but don't quit the completions window.
