I'd assume I use the reflection library for this, so possibly 1-2 people would know, but any hints on using this? I could probably Trial and Error figure out all but the CompletionInfo array stuff, but this could be a useful function. I was going through all of the InputType flags I want to use in my class and the Type_Text_Flag_Auto_Complete paragraph mentioned it. It would work nice to have some way of providing autocomplete values in the class.
The docs seem to indicate that it is the view calling it when text changes to present completions of its own and the flag is letting the keyboard know to expect them and not show its own.
