I have a "tags" field that will hold a comma separated list of tags, like many forums and blogs use. I would like to use autocomplete to help with the last comma separated entry. Example:

"Politics, Funny, Stu" will fetch "Student, Stupendous, Stupid ", etc.

And selecting one of the options will only replace "Stu".

I think I can use the search event to pull out "Stu", and I think I can use the select event to replace only the last comma separated entry.

First question: Does autoselect already do this and I'm just overlooking an option? Second question: if it does not do this, is there a more detailed example on using these events, especially the search event and adjusting the search string?
