Left/Right arrows to turn. Up arrow to move forward. This just demos how to create walls that your sprite can't walk through. How: It uses the "touching color" block to see if the ladybug is touching the color black. So you just draw your walls (or any objects) with the color black on its edges and the ladybug won't walk through them. You can change the touching color to whatever color you want (doesn't have to be black). It also uses 2 variables to keep track of the ladybugs previous X,Y position. That way, if she touches black, the code just moves her back to her previous position.
