scrollbars for a stack?

[Peter Brigham]

Here's one solution, no scrollbars but allows scrolling using the
scrollwheel or two-finger touchpad scrolling if available. Put the
following into the card script of your stack (or the stack script if more
than one card):

on rawkeydown what
  put the top of stack "myStack" into t
  if what = 65308 then -- scroll down
    set the top of stack "myStack" to t-12
    -- adjust the parameter as desired
  else if what = 65309 then -- scroll up
    set the top of stack "myStack" to t+12
  else
    pass rawkeydown
  end if
end rawkeydown
