Event handler for Button, Document and Link

The onMouseDown event handler is used to execute specified Javascript code whenever the user depresses a mouse button. onMouseDown uses the following properties of the Event object:
type - indicates the type of event.
target - indicates the target object to which the event was sent.
layerX, layerY, pageX, pageY, screenX, screenY
   indicate the cursor location at the time of the MouseDown event.
which - 1 represents a left mouse click and 3 a right click.
modifiers - lists the modifier keys (shift, alt, ctrl, etc.) held down when the    MouseDown event occurs.


<P>Click on <B><A onMouseDown="changeColor()"> green</A></B> to change background color.</P>

For example, with this code, the user can click on the word 'green' to alter the background color to green. Depressing the mouse button calls the 'changeColor' function to do this.
