I see that there are other fields involved, but in any case, check out the
"arrowKey" message in the dictionary. It can be used in place of your mouseDown
message. You can determine the selectedLine and then use the arrowKey
parameters to know which way the user went.

on mouseDown
global globalFrom
put word 2 of the clickline into globalFrom
end mouseDown
In the second list field (To), I have the following script:
on mouseDown
global globalFrom
global globalTo
put word 2 of the clickline into globalTo
if globalFrom > "" and globalTo >""
then put globalFrom,GlobalTo into theMatch
else
answer information "Please make a selection from both list boxes"
end if
put the dist["travel"] of field "data" into theMatch2
repeat for each line theMatch2 in the dist["travel"] of field "data"
if item 1 to 2 of theMatch = item 1 to 2 of theMatch2 then
put item 3 theMatch2 into field "results"
exit repeat
end if
end repeat
end mouseDown

Subject: A question about using Arrow Keys in a Listbox
I am using Rev. 4.0. I have a mileage app that has two list fields: From and To
In the first list field (From) I have the following script:
on mouseDown
global globalFrom
put word 2 of the clickline into globalFrom
end mouseDown
In the second list field (To), I have the following script:
on mouseDown
global globalFrom
global globalTo
put word 2 of the clickline into globalTo
if globalFrom > "" and globalTo >""
then put globalFrom,GlobalTo into theMatch
else
answer information "Please make a selection from both list boxes"
end if
put the dist["travel"] of field "data" into theMatch2
repeat for each line theMatch2 in the dist["travel"] of field "data"
if item 1 to 2 of theMatch = item 1 to 2 of theMatch2 then
put item 3 theMatch2 into field "results"
exit repeat
end if
end repeat
end mouseDown
The script works great when the user clicks on a line in the first field and
then clicks in a line from the second field, which displays the mileage between
two points in a field "results". I would like to implement in the second list
where the user could simply use the arrow keys to go up or down and display the
mileage for difference locations in the second list. How can I do that?
