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.
Rube Goldberg is spinning in his grave! Why would you want a short,
elegant solution when you could have a complicated one that took you
an hour to perfect!
