What is Macintosh equivalent of relaunch handler?

[Martin Koob]

I checked the LiveCode dictionary in my hot off the press PDF version to see
if there was more info on what data request AppleEvent data could give.   I
found a reference to

For more information about Apple events, see Apple Computer's technical
documentation, Inside Macintosh: Interapplication Communication, located at
http://developer.apple.com/documentation/mac/IAC/IAC-2.html.

Once I saw 'Inside Macintosh' I suspected this is a dead link.  I found that
is already noted in bugzilla -
https://quality.livecode.com/show_bug.cgi?id=20022

I did a quick search on and found this in Apple's documentation 
https://developer.apple.com/documentation/coreservices/appleevent.  Should
this be the link for that dictionary entry?
