I didn't read through your whole script, but here is a skeleton outline 
of one way to handle the behavior, you can adjust it for whatever else 
you need to do:


local lUserKeys, lOldTicks

on keyDown  whichKey -- select from keyboard
   if (the selectedField is not "") or (charToNum(whichKey) is among the 
items of "28,29,30,31") -- arrow keys
   then pass keyDown
   if the ticks - lOldTicks > 60 then put "" into lUserKeys -- adjust 
time here
   put whichKey after lUserKeys
   put return & fld activeFld & return into tListText
   get lineoffset(cr&lUserKeys,tListText)
   if it > 0 then set the hilitedline of fld activeFld to it
   put the ticks into lOldTicks
end keyDown

Note the user of a local script variable outside the handler 
declaration, rather than a global.
