To set brush dynamics for graphics tablets

You can use a graphics tablet with each paint tool. You can adjust the brush tip by using the graphic tablet's pen
pressure, pen tilt, or position of the pen thumbwheel. Specify brush dynamics options in the Brush Tips panel to add
dynamic (or changing) elements to brush tips. For example, you can change the size of your brush tip dynamically
by adding more or less pen pressure. Pressing the eraser side of the pen to the tablet always selects the Eraser tool.
Note: Brush dynamics are available only when you're using a pressure-sensitive digitizing tablet such as a Wacom tablet.
