It is ultimately a user choice whether "less" or "more" is used by the
manual pager. The only reason "more" is used as the default is because
it's a required component of the base system. Less is twice the size of
"more", which is why "more" is in the base system rather than "less".
I suspect that more could be taught to back up easily enough. I was
surprised to find that less has more options than "ls", and if you read
its manual page it looks as if it is intended to emulate an editor.
For a more functional presentation of the manual, I'd convert the manual
pages to HTML on the fly, and read them with lynx or another web browser.
Thanks
