To move the players, position your cursor over the players (1, 2, 3, 4), click on the player and keep your mouse button down. Drag the player to the court position you wish and then release the button.
Lines and Boxes:

Setup: To draw a line, first choose the color and line width you desire using the controls located on the right hand side of the control area:

Next, click on either the "Straight Line", "Arrow Line", "Pencil", or "Box" button in the upper left portion of the tool bar. "Straight Line" and "Arrow Line" both draw straight lines, and "Arrow Line" will draw a line with an arrow head at the end of the line.
Draw: For "Straight Line", "Arrow Line", and "Box" position your cursor on the court, click or depress the mouse button once and drag the line the length you wish. Release the button to terminate the line or box.
If you click on the "Pencil" button, then click or depress the mouse button on the court then a line will be drawn as you move the mouse. Release the button to stop drawing.
Curve: 
Setup: To draw a curved line, first choose the color and line width you desire using the controls located on the right hand side of the control area:

Next, select the "height" of your curved line, from small to extra large. Then, select where the curved line will peak, which will help you illustrate the correct path of the ball for a particular shot. For example, a line drawn with the defaults of "Small" height and "Middle" peak position would look like this:
A line drawn with a height of "Extra Large" would look like this:
And a line drawn with a height of "Extra Large" and a peak position of "Far Right" would look like this:

Draw: Once you've selected what kind of curved line you wish to draw, position your cursor on the court, click or depress the mouse button once and drag the cursor the length of the curved line you desire. Release the button to terminate the curved line.
