Here's a link that displays the man page for the grep command:
Refer to the <link grep Man> grep(1)<\link> command.
"Man" is a keyword for the <link> element, so if you want to create a link that displays the man page for the man command, you must use the hyperlink parameter:
Refer to the <link hyperlink="man" Man>man(1)<\link> command.
To display a man page in a particular section, precede the man page name with the section number. The following link displays the "mkdir" man page from section 2 (which is different from the man page of the same name in section 1):
Refer to the <link hyperlink= "2 mkdir" Man>mkdir(2)<\link> command.
