David, C-v is how you scroll one-page-at-a-time, so with numerical arguments ( "C-u 1" [ or "Cu -1" ] ), here is how I would do it: C-u 1 C-v for "up", and C-u -1 C-v for "down" .

In VI, C-e (C-y is the counterpart), 1. scrolls the page up by line, AND 2. moves the up cursor ALSO by one line - so that it stays at the same character at which it was originally. In the lisp examples (thanks for them!), I commented out "(previous- line 1)" and "(next-line 1)" to achieve this. I *do* also like what your original lisp samples do. ^ permalink raw reply [flat|nested] 13+ messages in thread
