  	@(#)IsKeybdFocus.c	1.7.1.1	Date:1/22/91
  	Author: TAT
	History:
            05/30/90 SJS add to sccs
            09/23/90 SJS the focus region only need be a descendant.
	Calls:

	Summary:
            Returns True if current focus object matches the specified object
        type (relative to the current object). The objecttype passed in is a
        concatenation of the object types from the parent on down to the one we
        are interested in. Thus, from the keyboard region we go upwards from
        object to object. As we travel up the ancestor chain, each object type
        is compared against the corresponding "piece" of the concatenated type.

        INPUTS:
            none
        
        OUTPUTS:
            none

        RETURNS:
            True = focus object matches specified object type
            False = no match
