You are trying to use emacs as standard word processor. Emacs keeps
the pointer always visible.
Here you are not supposed to "scroll", but move the _cursor_ to
navigate. There are plenty of commands to do so. M-v, C-v to page.
M-{, M-} to navigate between paragraphs. M-<,M->  start end of a
buffer see http://www.gnu.org/s/libtool/manual/emacs/Moving-Point.html
for more.  Also don't forget C-s, C-r.

The one you need is C-M-b, C-M-f to navigate between balanced
expressions. Place you cursor after ) or } and press C-M-b and then
C-M-f to return.

Also if you plan to come back to the same point just press C-space
C-space then move, and when decide to come back just press C-u
C-space.

HTH.
Vitalie.
