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

Solution 1:

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.

Solution 2:

Type :n and :p.
