Hello,
After reading (info "(emacs) Scrolling"), I think the Emacs
terminology for specifying scrolling directions is pretty confusing:
1. The terms "up" and "down" have the opposite meanings of the ones
commonly used in the (non-emacs) world. The info node explains that
this is for historical reasons; OK, but then, why don't we try to find
a solution? (see below)
2. The terms "forward" and "backward" are used as synonyms for "up"
and "down" respectively. I guess this was an attempt to mitigate the
previous problem [*], but IMO it worsens it, because:
(a) They are ambiguous: here we are talking about _vertical_
scrolling, and "forward"/"backward" could refer to horizontal
scrolling too.
(b) They take the opposite criterion: while "up"/"down" refer to the
movement of the text (relative to the window), "forward"/"backward"
refer to the movement of the window (relative to the text). So we end
up with a confusing mix of criteria.
So here is my proposal for solving these problems:
1. Rename the command `scroll-up' to `scroll-window-down' (an
unambiguous name, which uses the standard approach of describing the
window movement), and define `scroll-up' as an obsolete alias for
`scroll-window-down'. Likewise for the rest of scroll commands with
"up"/"down" in their names.
2. Remove the use of "forward" and "backward" to refer to scrolling directions.
WDYT
