Understated description for a massive implementation. There's a thread in tutorials, scripting runtime information, that didn't make much sense to me until I browsed the files on this.
I thought the autocomplete was just command history but it's apparently the entire global context. I wondered where he got that from and then reread that thread. Oh, that's where. I posted a review earlier with a bit about a help command would be nice, but knowing where it came from that's not really needed. So I deleted that and posted a new review.
Excellent tool.
In terms of where to find - the easiest would be look to for capitalized objects in the outer most tab complete - i.e. within the window.
