Another question. I would like to be able to set/kill a timer for any cell in a 
Grid. My paradigm is:
   
  1. Get the focus for a cell (_GotFocus()) & set the timer
  2. Honor the timeout if the event is present & kill the timer, or
  3. Lose focus for a cell (_LostFocus()) & kill the timer.
   
  But, I can't find a way to get the focus for a cell, only for the grid. There 
is no associated _GotFocus(), _LostFocus() for cells. Am I missing something?
   
  Background. With the capability to associate a timer with a cell, I can 
simulate tooltips and present the user with help. In particular, help 
associated with a fixed cell (intersection of a fixed row and a fixed column) 
allows generic help on an input field.
