Devin,

Would something like this work:

on mouseMove pX, pY
	if word 1 of the target is "field" then
		if the mouseChunk is not empty then
			get the linkText of the mouseChunk
			if it is not empty then
				set toolTip of the target to it
			else
				set toolTip of the target to empty
			end if
		end if
	end if
		
	pass mouseMove
end mouseMove

It just sets the tooltip of the field to the linkText which will  
appear below the cursor.
