don't mark as read automatically

[jidanni@jidanni.org]

How can one manipulate around the Summary buffer without marking
articles as read automatically? Yes I want to mark some articles as
read, but only explicitly via e.g.,
   d runs the command gnus-summary-mark-as-read-forward

Anyway I have to use gnus-summary-clear-mark-forward lots these days:
SPC SPC <up> <escape> u <escape> u

I checked the code and the concept of marking things as read the
moment one sees them seems quite ingrained.

Imagine two boxes on your desk, "Inbox" and "Already processed".
Well, I'd like to poke around the Inbox without moving things to
Already processed without actively saying so.

Anyways, of the various states of an article, R O E etc., I don't want
the R to be automatic. Flags only set when I say so! (Except R
becoming O which I like.

P.S., the docstring of
(defun gnus-summary-scroll-up (lines)
  "Scroll up (or down) one line current article.
  Argument LINES specifies lines to be scrolled up (or down if
  negative)."
doesn't mention that it also selects an article.
