When entering information to a prompt:

   - If entering a keyword, such as the directory service type, the keyword
     can be entered using either upper or lower case, and can generally be
     abbreviated to three, or sometimes fewer, characters.

   - If entering user-supplied information, such as node names, enter the
     string with no abbreviations.  Some information, such as node names in
     particular, must be entered in the appropriate case.

   - Entering a question mark (?) to any prompt in a form provides help
     information on that form, with sub-topics for the various fields in
     that form.
