That was originally the primary motivation, and then once I saw I could 
do that, I didn't think to look beyond.  Hence, I completely forgot 
about #anchorWithAction:text:, even though I had used it before.

However, I think even this use should probably be revisited, because the 
original motivation for having external links cause a method to be 
invoked was because of the desire to have multiple entry points into an 
application (i.e., static URL's).  This would yield bookmarkable URL's, 
plus the ability to email a URL to someone that would enter the 
application at a known point when they clicked the URL that they were 
emailed (in such a case, they would not have a preconfigured bookmark, 
nor would they necessarily have ever entered the application before).

But, I suspect the WARegistry stuff could do the same thing.  I'm just 
not clear on how to use it that way.  Do you have any pointers or sample 
code that more fully explains how to use the WARegistry?
