Hello kiln,
I don't have a Access example but maybe an Excel example is OK for you to
have a look at:
1.Download the example from:
http://www.help-info.de/en/Visual_Basic_Applications/vba.htm
2. Unzip the files, have a look at the "Security Updates" note and read
here:
http://www.help-info.de/en/Visual_Basic_Applications/vba_using_example.htm
Note there is a API call for the buttons ("Show help Context 10000 (API
call") - I think that's the call you are looking for.
You know - there is a link for the "Table of Contents" below the search
input text box in Access or Excel's default application help file (Main
Window F1 help).

Best regards
Ulrich Kulle
