BTW you will not find that little hint by reading the man pages, because it's not in the man page.
That's because the man pages don't know what program you're using as the "pager", and so can't give you the options.
Look in /usr/lib/man.conf, or wherever your distro keeps it, find the "PAGER" option and see what is used for your distro. You can then use any
of the commands supported by that program.
