DESCRIPTION: Automatically jumps the focus to the next field  
  in the tab sequence when a specified number of character is entered.  

PARAMETERS: 
  input - Text INPUT field to be tested.  
  len   - length of input before autotabbing.

  To use, include the following code as an inline event handler
  in an INPUT text field:
	 onKeyUp="return autoTab(this, n);"  
  where n is a number specifying len. 
    
RETURNS: 
  True if tab is made.
