simulate keystroke

[Mark Schonewille]

Larry,

This has nothing to do with focus. You should change your approach.  
The following makes your script slower, yet much more responsive.

Create a button with a mouseUp handler, which calls a main handler.

on mouseUp
   set the hilite of btn "Switch" to true
   foo fld "Very Long List"
end mouseUp

Put the following in e.g. the card script. This handler calls itself.

on foo theVeryLongList
   if the hilite of btn "Switch" is true then
     -- do something here with line 1 of theVeryLongList
     -- and delete that line. You might use a completely
     -- different approach here if you want.
     delete line 1 of theVeryLongList
     send "foo theVeryLongList" to me in 0 millisecs
   end if
end foo

Add a checkbox named "Switch". This button doesn't need a script.

If you click the first button, the switch will be turned on and the  
foo handler will run. When you click the checkbox, the foo handler  
will stop running.

You can also make a switch without another button. Just make a  
checkbox with the following script.

on mouseUp
   if the hilite of me then foo fld "Very Long List"
end mouseUp
