=================================================================
An EXCELLENT tutorial on event basics can be found at:
http://www.quirksmode.org/js/introevents.html
=================================================================
You can access the following properties thru the event handler:
Available Properties
altKey Retrieves a value that indicates the state of the ALT key.
altLeft Retrieves a value that indicates the state of the left ALT key.
clientX Sets or retrieves the x-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.
clientY Sets or retrieves the y-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.
ctrlLeft Sets or retrieves the state of the left CTRL key.
offsetX Sets or retrieves the x-coordinate of the mouse pointer's position relative to the object firing the event.
offsetY Sets or retrieves the y-coordinate of the mouse pointer's position relative to the object firing the event.
returnValue Sets or retrieves the return value from the event.
screenX Sets or retrieves the x-coordinate of the mouse pointer's position relative to the user's screen.
screenY Sets or retrieves the y-coordinate of the mouse pointer's position relative to the user's screen.
shiftLeft Retrieves the state of the left SHIFT key.
srcElement Sets or retrieves the object that fired the event.
type Sets or retrieves the event name from the event object.
x Sets or retrieves the x-coordinate (in pixels) of the mouse pointer's offset from the closest relatively positioned parent element of the element that fired the event.
y Sets or retrieves the y-coordinate (in pixels) of the mouse pointer's offset from the closest relatively positioned parent element of the element that fired the event.
The captureEvents() method captures all the events of the event type passed.
When you have multiple events to capture, separate them with the pipe, |, character.
Here are the types of event you can capture:
Event.ABORT
Event.BLUR
Event.CHANGE
Event.CLICK
Event.DBLCLICK
Event.DRAGDROP
Event.ERROR
Event.FOCUS
Event.KEYDOWN
Event.KEYPRESS
Event.KEYUP
Event.LOAD
Event.MOUSEDOWN
Event.MOUSEMOVE
Event.MOUSEOUT
Event.MOUSEOVER
Event.MOUSEUP
Event.MOVE
Event.RESET
Event.RESIZE
Event.SELECT
Event.SUBMIT
Event.UNLOAD
