Synopsis

Description

The documentation corresponding to the keys in the list returned can be displayed by applying the function help to it. To see the documentation corresponding to just one or some of the keys, give help an integer or a list of integers to be used as indices in the list returned by the most recent application of about. The functions viewHelp and infoHelp can also be given an integer for viewing the documentation.

The packages searched are the loaded packages and the packages installed under one of the prefixes listed in prefixPath. The first search will take a few seconds while it reads all the documentation keys into memory.

Caveat

Since s is taken as a regular expression, parentheses serve for grouping subexpressions, rather than matching themselves.
