5.2.2 Quick Tips for Using Online Help

Here are some tips for using the online help system:
1. Searches are case insensitive and your search string need only be a
substring of a keyword to make a match. Thus, for instance, to find
the section of the manual entitled
Commands and Functions for Polynomials, it is enough to type:
?for poly.
2. In general, it is best to start with short keywords in order to
maximize the number of matches.
3. If you cannot find a match using
?, try using
H.Command to
search by type. For example, suppose you are looking for a command
that will give the remainder of the division of one polynomial into
another. Trying
?remainder produces no matches. You know
that the command you are looking for operates on polynomials, so try
H.Command("poly"). It produces a list of a little over 30 commands,
among which will be listed:
* DivAlg  division algorithm.
4. The command
??keyword, with two question marks, will list all
matches even if
keyword exactly matches a keyword for the online
help system.
