Update: I just saw the post that JamesBrooks made. I forgot all about that. I will work on that. WOO HOO! I got it! Notepad++ now recognizes multiple calltips for functions such as AutoItSetOption!
As much as I enjoy using Scite, I do like the functionality provided by Notepad++. The previous is no longer true because SciTE is my first go-to for any text editing. Unfortunately, np++ does not provide calltips for AutoIt. So I hacked together a script to turn AU3.api into autoit.xml.
