This is a bug in the latest 2.7alpha.  (updates through 1660)

If you open a system browser in either Morphic or MVC, and try to select
"alphabetize" in the message category pane pop-up menu, you'll get a
"MessageNotUnderstood: alphabetizeMessageCategories" walkback.

(I guess this menu item is a new feature, it wasn't in 2.6.  Anyway, it
would be very useful if it worked.)

I'd call myself an artist
If I could make these feelings clear
But there's a million things to think about
When you're cutting off your ear
