Use arrow keys to move it around, and click to rotate. In the Sensing category of blocks there is a block which allows you to access properties of the Stage (like backdrop #) and properties of other sprites. However, by default you can't access properties of the sprite running the current code. Why would you want to do that? Well, it would be nice if clones could access properties of the parent sprite. And they can, using a block which return the name of the current sprite, like the "join" block, or a variable. See inside. You should also be able to select a property of your sprite in a second sprite, and then drag the block to your sprite. If that doesn't work, try the variable approach above (and inside). All code by me (@kriblo).
