sure, yes.  however, that's not the point i was trying to make:

the code to do that's there now, and would be a reasonable way to test
the speed improvement gained based on scrolling multiple lines at once.

However, even if the notion of deferring input until you have a
certain amount, or whatever, before processing it/scrolling/whatever
is implemented, the existing 'sun' behaviour of allowing multiple line
jumps should stay the same.  it's a long-existing and well-documented
part of sun consoles.  8-)
