autocomplete options default event

Whether the autocomplete options default event(mousedown or click) takes effect is changed to configurable, or the event is exposed and the logic can be rewritten

This topic is really too cryptic for me to be able to make anything of, sorry.

sorry, my description may be murky! i mean, Each option in the autocomplete prompt panel inserts content into the editor when clicked. Can this click event provide an extension, or provide an eventHandler so that I can customize multiple events and override the default ones here.

Only at the level of individual completions, by giving them a custom apply method.
