Handling arrow key moving from one line to another in a field

Hi Everyone,
I'm currently struggling with this problem:
I'm successfully filtering the lines of Field 2 with the text of field 1, and when the results are displayed in field 2, I'm wanting the up/down arrow key (
whilst I am still in field 1), to move up/down the displayed lines of field 2.
I've got as far as this for the down arrow key (which of course doesn't work - I'm assuming I'm not grasping the correct logic yet or have got my self muddled with the repeat loop?!)
Code: Select all
-- whilst I'm still in field 1:
on arrowkey theKey
repeat with x = 1 to the number of lines in field 2
if theKey is "down" then go to line x of field 2
pass arrowkey
end repeat
end arrowkey
Grateful for any hints etc.
Many thanks,
Kind regards,
Glenn

Hi Glenn,
are these LIST FIELDS?
Hint:
We cannot GO to a line in a field, we can select (=hilite) that line or set the cursor into that line.
So not sure what you want to achieve...
Best

Thanks Klaus,
Yes, its a field with a vertical scrollbar.
When I'm typing in field 1 I'm getting results being listed in field 2 as I type as a result of the field 1 filter.
To then select one of the result lines in field 2, I can just move the mouse and click on one of the lines of field 2, but for convenience I was wanting to handle the down arrow key to hilite the respective lines in field 2 whilst I am still sitting in field 1.
I guess in a nutshell what I'm trying to achieve is getting the up/down arrow keys to work on a 'remote' field from the field in which the arrow keys are being pressed.
(I hope I've not made it now even more confusing!)
Kind regards,
Glenn

Hi Klaus,
Whoa... whilst I was making a coffee the solution suddenly came to me....
Code: Select all
on arrowkey theKey
if theKey is "down" then focus on field 2
end arrowkey
This now enables me move up/down the lines of field 2 and I now just need to figure out how to handle the hilite but I think this should be straightfoward (famous last words!)
Thanks again for responding and being a listening ear.
Kind regards,
Glenn

Hm, a vertical scrollbar does not make a field a LIST field!
So are or are these field not LIST fields?

Just a normal field - I hadn't appreciated the difference!
