Here's mine (watch for line wrap):

local lOldTicks,lUserKeys
on keyDown  whichKey -- select from keyboard
   -- J. Landman Gay, 1990, modified for Revolution: 2003
   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
   put whichKey after lUserKeys
   put return & fld 1 & return into tListText
   get lineoffset(cr&lUserKeys,tListText)
   if it > 0 then set the hilitedlines of fld 1 to it
   put the ticks into lOldTicks
end keyDown
This allows you to type more than just the first character of a line to hone in on an exact line match. If the user pauses for more than a second (60 ticks) then the collected keystrokes are abandoned and the search starts over. You can adjust the timing by changing the "60" to something else.
