- >There's GOT to be a reason to choose one frame of reference over another.
-
- Well, what if one reference uses "scroll" and the other uses another
- word? For "scroll-up" I imagine the text moving upwards on the screen,
- as if it were being scrolled by (ala player piano, etc).
- Now if it were "page-up" I would not find it hard to imaging a different
- thing happening, such as the window into the text moving up.
-
- > Ok, here's a good reason for preferring vi's way over emacs's: when
- >you're in a scrolled window in a GUI and you click on the down-arrow
- >in the scrollbar, what happens? You move down through the document!
-
- Hmm, I bet you're still in your twenties :-) Imagine using a GUI
- as an analogy for something! (I've only been 30 for a month, and
- I'm still boggled) The people that wrote emacs didn't have GUI's
- as a reference, and very few other screen editors to steal ideas
- from. "Scroll-up" was a very appropriate analogy back then.
-
- >The same if you drag the block in the middle of the scrollbar
- >downward. Do any of you think this is ambiguous or counter-intuitive?
-
- *Only* because I have used scroll bars in their common setup for
- so long, *not* because it is a natural way of doing things. (ie,
- when the bar moves up and down, is the window moving over the text,
- or the text moving under the window?) Since the window does not
- *look* likes it's moving, it would seem natural to imagine that
- the text underneath is moving (and moving the text UP gets you
- closer to the bottom of the text).
-
- >How about the PageUp/PageDown keys on many keyboards?
-
- "Page" is not the same as "scroll" - and I think that's 99% of the
- confusion.
-
- >How about the
- >up-arrow key -- what word-processor ever used it in any way to do
- >what scroll-up does? Would you expect Shift-UpArrow to move to the

-
- This is a moot point. People DO NOT type "scroll-up" in emacs, they
- use a key stroke instead. All you need to know is Control-V is down,
- and Meta-V is opposite.
-
- > It seems to me that there's a very strong convention of moving
- >"down" meaning moving to a later part in the text; i.e. the observer
- >is moving, not the text.
-
- Uh, emacs should change because all the new squirts on the block
- decided to use different names? And even if emacs changed, it's
- not big deal, since no one ever types in that function name unless
- they've reached the point where they won't get confused.
-
- Next there will be this silly argument that "execute-extended-command"
- should be called something else, since that isn't the name VI uses.
-
- >I just think that for the sake of intuitiveness and consistency,
- >the names scroll-up and scroll-down should have been chosen the other
- >way.
-
- At the time, picking either way would NOT have affected consistency
- since there was not much to be inconsistent with. And the intuitive
- argument is invalid.
