Thanks Devin and Mac - that works fine.

P.S. I'm not sure how I would *ever* have found that in the dictionary /
User Guide - so thanks again.

This works for me, though you might need to adjust 'tStepsize':
--in group script
on rawKeyDown pKey
if the short name of me is not in the long name of target then
pass rawkeydown
else
put 45 into tStepSize -- adjust here the stepsize for scrolling
switch pKey
case "65309" -- scroll up
set the vscroll of me to the vscroll of me - tStepSize
break
case "65308" -- scroll down
set the vscroll of me to the vscroll of me + tStepSize
break
end switch
end if
pass rawkeydown
end rawKeyDown
(In light of the recent copyright discussion going on here, I would like to
disclose that I 'borrowed' this entirely a few years ago, and can't remember
where; so apologies and thanks to the actual author.)
There are also a few similar examples in the "rawkeydown/up" entries in the
Livecode Dictionary.

On OSX (10.8.4, MBP - but I doubt that matters), I can scroll using a
two-finger touch (i.e. if the cursor is within an area that is scrollable, then
generally I can touch with two fingers, and 'push up' or 'pull down' the window
contents.
This includes LC fields - this scrolling "just works" for them.
If I create a group, set and lock its position and give it a scrollbar, then it
gets the scrollbar, and all the traditional behaviour associated with that
(i.e. the scrollbar can be dragged, etc.)
But it doesn't automatically get the two-finger touch behaviour.
Is there some way I can enable that ? Do I need to program this myself ?
It looks as though the "touchStart, touchEnd, etc. are implemented on mobile
only, so I'm not sure where to start.
I believe you have to handle scroll wheel actions using rawKeyDown or rawKeyUp
(I forget which, and I'm not in a place I can check right now.) Just figure out
which codes get sent when the scroll wheel is used and set the scroll of the
group in your handler.
