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.
