There are certainly weaknesses in the Blitz documentation (although I find the Blitz documentation much better than that of most software) but that isn't relevant to this thread. There really isn't any way for the documentation to be any clearer about the AppTitle command. Not only does the documentation entry explain what the command does, it has an example of it's usage in code. Also, the entry can be searched for in the documentation a couple different ways, including categorically and alphabetically.
