Can you make it easier to resize windows on Ubuntu?

In Linux, you can usually hold Alt and drag the right mouse button near one of the borders to resize a window, and hold Alt and the drag the left mouse button anywhere in the window to move it. I can't say for certain that this works on Ubuntu though!

Edit: This is based on my experience with fluxbox/openbox. There should be similar shortcuts for other window managers. According to this link, this should work with KDE. This link suggests it would be Alt-F8 for GNOME.

Hold Alt and press Middle click (mousewheel) near the edge of the window and drag to resize it.
