WASD to move Up/Down arrow to change size space to change costumes
In scratch 1.4 you can right click the screen and capture screen region and select the entire window as a costume. When you bring it up to 2.0 and 3.0 it automatically sets the size to 53% to prevent crashing from too large of a sprite. If you want a large map with a single sprite you are better off going with a 480x360, the regular max size since that can go much larger in size for some reason. If you are stitching many sprites together I think the regular max size is also best since its easy to optain
