An EXCELLENT tutorial on event basics can be found at: |

================================================================= |
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. |
