I hardly use info myself since I find it so frustrating. Using
an html document offers you better navigability than info but I
still find it severely lacking compared to what less or vim
offer. Again the problem is that if you are reading a long page
which occupies several screenfuls a web browser does not offer
you a way to mark your place on the page so that you can get
back to it quickly. Or at least I've never encountered one which
does. So you have to memorise the approximate position on the
scrollbar and later on middle-click on that position to arrive
at that approximate place and scroll up and down until you find
the precise point you want. A right PITA.

With Emacs info mode if you follow a link and then go back (with <l>)
the cursor is right at the link point. Concerning HTML,
terminal-based web brosers work in the same way. And even for GUI web
browsers (which don't have a cursor in read-only text), if I follow a
link and then go back, the page is normally in the same position it
was in originally (unless I changed the window size in the meantime);
at least that's my experience with the browsers I have used (lately
mostly Mozilla).

But I wasn't talking about links, I was talking about reading
one long page which may or may not have links. If I find a
point in the page I want to refer to quickly then with less or
vim I press m followed by any letter which makes the letter a
mark for that particular point. For example mb makes b a mark
for that point in the page. Then when I want to return to that
point quickly I will do 'b and I'm right where I want. That's
one functionality I'm missing with info but I have with man
pages which I read with less.

Note that even when following links is involved, which is the
case with info pages, a similar facility would be useful. Say I
follow links which take me from page1 to page2 to page3 to
page4. If I want to return to page1 I have to click on the back
arrow 3 times. What I want instead is to be able to mark my
position when I am in page1 and with a couple of key presses
return to the point in the page where I placed the mark. It may
be that that point is not the place where the link to page2
exists but some other point which I find especially relevant.

you've probably misunderstood what I've said.
