changing alt-tab behaviour? (how do I..)

[william maddler <news maddler net>]

Hi all!
I'm giving a try to Gnome since a couple days. I'm kida satisfied, but
I'm missing a couple features:

1) having alt-tab cycling all windows, and not only those on current
desktop;

2) disable the frame shown around windows when alt-tab gives focus;

is there a way to fix that?

Thank you.
