RE: C-p, C-b, C-f, and C-n... why?

[Drew Adams]

        There are several ways you can do this.  You can use the arrow
        keys or you can use C-p, C-b, C-f, and C-n.  The latter can be
        more efficient in some situations, because it keeps your hands in
        the standard position.  These characters are equivalent to the
        four arrow keys like this:

 You can use the arrow keys or `C-p', `C-n', `C-b', and `C-f':

   [up],    `C-p' - blah blah
   [down],  `C-n' - blah blah
   [left],  `C-b' - blah blah
   [right], `C-f' - blah blah

That says everything that needs to be said. There is no need to explain the
clever design, make claims about efficiency, or reference "standard
position" (do you wonder what that is?).

People are smart enough to pick the alternatives they like. The important
thing here is to let them know 1) that there are alternatives, and 2) which
alternatives correspond to which.
