Emacs 21.2 : Can you set it up so the cursor is focused in completeion buffers when they happen?

[Steve]

Hi;

I'm using gnu emacs 21.2.

I was wondering if there was something I could set so that when a
completeion buffer comes up ( ie C-h,  M-occur ) the cursor will be in
that buffer?

I usually want to scroll such lists so if I could set things up like
this it would save me a few keystrokes.
