Here's an alternative approach - it's great to have alternatives! I believe that to "stop and fade out a rolling title" is what the Roll/Crawl Options box is all about. Here's what I do:
Create a Default Roll Title.
In Roll/Crawl Options click on Start Off Screen (Preroll will disable) and enter the following values: Ease-In: 0, Ease-Out: 50 and Postroll: 100
Leave End Off Screen unticked
Make a few space lines before and after whatever it is you want to have stay on the screen at the end so that it fits in the middle. In my case that's usually ME! :-)
Your titles (as long as you like) will start off screen and then they will roll and roll until that last block appears and slows down - the Ease-Out value. That will stay on the screen for the Postroll value duration. Usually I have a normal disolve transition to do the fadeout. All done in just a few mouse clicks.
(The above values are what I use 99% of the time but you might wish to experiment.)
