How to enable dragging windows with alt-click in gnome 3 / gnome shell

Question

Dragging windows around with alt-click has always been one of my favorite features on a linux desktop: no need to aim at the window title to drag, just press alt, click anywhere within the window and drag.

This seems to be disabled in gnome 3 / gnome-shell in debian testing. How can I enable it? (I hope the feature still exists...)

Answer 1

This did what I needed:

gconftool-2 --set /apps/metacity/general/mouse_button_modifier --type string "<Alt>"

I figured it out based on another question: Gnome3 - Change window drag shortcut

It seems that alt-click-drag is usually enabled and I found several questions wanting to disable it. My case was the opposite. The feature was disabled, and I really wanted to enable it.
