Not aware of a list, though Ken's got a page on the Omni site that has links using this same mechanism to activate a bunch of debugging operations, such as resetting the keychain, rebuilding the database, etc.
If you successfully click on one of these links in Safari on your iPhone or iPod Touch, OmniFocus launches and you do get a notification that something is happening.
In this particular case, despite saying it will quit, it doesn't.
