AutoCAD 2006 and 2007 feature a hidden shortcut that let you copy and move objects directly -- without using the Move/Copy commands or the tedious grips editing method. You select an object, and then drag it by the right mouse button. When you let go, a shortcut menu appears that lets you chose from Copy Here, Move Here, Paste as Block, or Cancel.
AutoCAD 2008 does the same thing. But if you use the left mouse button, it moves the object (without the shortcut menu appearing):
1. Select an object.
2. Grab it on a non-grip location with the left mouse button (avoid the grips).
3. Begin dragging the object. Notice that there is a slight delay, and then the object begins moving with the cursor.
4. Let go of the mouse button. The object is in its new location.
