- Wait for the applet to fully load. This may take some time. The applet only becomes active once the status bar (bottom-left) says 'Applet started'.
- Red points can be moved: Place the cursor on the point, left-click, hold and drag ...
- If there is a button in the applet, click the button to make objects move, or new objects to appear or disappear. (If a button stays down when you click it, click it again to stop the movement, and click again to continue ...)
- When objects are moving, press '>' on the keyboard to speed up the motion or '<' to slow it down - remember to use SHIFT!
- Press 'r' on your keyboard to reset the sketch to its initial setting. If the applet is not active, first click anywhere in the applet, then press r.
- If an object is traced, click the red 'X' button in the lower-right corner to clear traces.
- The '?' button in the lower-right corner is a link to the JavaSketchpad homepage.
Note: Length measurements are given in pixels (short for picture element). A pixel is a single dot on the computer screen.
