Quake3World

I've tried this guide but it looks like Radiant 1.5 doesn't have the option of ctrl + lmb to distort brushes, guys know of any other guides for making terrain or how its done in 1.5?

In 1.5, select the brush or brushes. Press E to bring up edge mode. Shift and LMB to drag a selection box over the edge control point or points...drag with the mouse.
It's quite esay.
