Description
Responds to a keyword-based Help request.
The Help System calls UnderstandsKeyword to determine whether the Help Viewer can provide Help topics for a keyword-based Help request based on HelpString
. UnderstandsKeyword should return the number of Help topics that match the request. If the Help viewer does not support help on this keyword, UnderstandsKeyword should return zero.
