Re: Emacs 22.1 does not redisplay while holding down Prior key (scroll-down)

[Richard Stallman]

    When holding down the Prior key (usually labeled ?Page Up?) which is
    bound to scroll-down to scroll toward the start of the buffer, no
    redisplay occurs until the beginning of the buffer is reached.

    I see the same problem with Emacs from CVS from 2005-02.

    In Emacs 21.4, redisplay occurs after every movement with both keys,
    as expected.

This probably is due to a slowdown in redisplay compared with Emacs 21.

If someone figures out the cause of the slowdown, maybe we can speed up
that case.
