HyperCard: Disabling Arrow Keys while Keeping Text Arrows (8/93)
To disable navigation through a stack with arrow keys, while still allowing
arrow keys to be used in a field, put the following handler in the stack or
background script.
on arrowKey
if the selectedField is not empty then pass arrowkey
end arrowkey

arrowKey.
