I have a list field, and as I use the Up and Down keys, I want to
display the contents of individual lines in another field. The list
field's handler below displays the lagged line and not the one that
was keyed to because the selected line doesn't change until the pass
arrowKey command is invoked and that has to happen at the end for the
line to change.
Not sure how to get what I want.

on arrowKey theKey
if theKey is "Up" or theKey is "Down"
then
put the value of the selectedLine of the target into fld "Display"
pass arrowKey
end if
end arrowKey
If you trap the selectionChanged message instead of arrowKey, you'll not
only get the message when you want it but also have an update when the
mouse is used to, from the same handler. You can also get the value of
the selected line by using the hilitedText property:
on selectionChanged
put the hilitedText of the target into fld "Display"
end selectionChanged
Also, the "left" and "right" arrow keys have the same automatic behavior
as "up" and "down" respectively, so this selectionChanged handler will
handle those as well.
