Description
The command shows which manual sections contain instances of any of the
given keywords in their title. Each word is considered separately and
the case of letters is ignored. Words that are part of other words are
listed. Thus, looking for the word compile hits all instances of `com‐
piler' also.
If the line starts `name(section) ...' you can do `man section name' to
get the documentation for it. The following command line lists all
commands that have to do with formatting:

To then access the reference page for the printf subroutine that you
see listed, type:
man 3s printf
The command is actually just the -k option to the command.
