less command with multiple files: How to navigate to next/previous

We read in the manpage:

       :n     Examine  the next file (from the list of files given in the com‐
              mand line).  If a number N is specified, the N-th next  file  is
              examined.
       :p     Examine the previous file in the command line list.  If a number
              N is specified, the N-th previous file is examined.

Type :n and :p.

Found out from :h (help window) that I can use :p (for previous) and :n (for next)
