Hold it. That code, as written, will trap *A*L*L* rawKeyDown events, and
silently kill everything that's *not* a scrollwheel-down event. Which, in turn,
means that text input is toast, among other probably-unwanted side-effects. Try
something like this instead:
on rawKeyDown DerKey
switch DerKey
case 65308
DoScrollDownStuff
break
case 65309
DoScrollUpStuff
break
default
pass rawKeyDown
end switch
end rawKeyDown
Note that with the switch structure I've used here, there are a number of
perhaps-useful tricks you can pull… but said tricks are strictly outside the
scope of the original "how do I detect scrollwheel activity?" problem, so I
will leave said tricks as exercises for the reader.
