1 - Select mode 1 (press space or press down the mouse to start drawing, press again to stop). 2 - Select mode 2 (tap and hold to draw, DOES NOT WORK WELL). 3 - Select mode 3 (Basically mode 1 but you use arrow keys to draw). Enter/Return - Delete ALL art. Slide opacity to change pen transparency. Slide brightness to change pen brightness (the lower the number, the brighter... for some reason). Slide darkness to change pen darkness (the lower the number, the darker). Slide the color slider to change pen color. Slide the size slider to change pen size.
Note: PALETTE DOES NOT WORK, so I guess it's for decoration
