By "right click to get the motion back" you mean right clicking and dragging to move the vertices? Don't do that, after you select the vertices you want to move, make sure your mouse pointer is inside the 3D window, press "G" and move them, when you get them where they need to be you can then left click to confirm placement or right click to cancel. Im somebody who easly overlooks small hotkeys and such, yea you pretty much hit it on the head. The whole time I was just trying to move using the RMB, even though it should have it, never dawned on me to go thru the keyboard and try em all lol. Blender is pretty confusing at first, but kudos to you friend much appreciated. Now on with the blending.
