Invoking JavaScript -- event handlers

onLoad	browser loads page
onUnload	user leaves page
onMouseOver	user moves cursor over A link
onMouseOut	user moves cursor off A link
onClick	user selects button or link
onSubmit	user submits form
onFocus	user moves focus to object (usually a text box)
onBlur	user removes focus
onChange	user changes value of object
onSelect	user highlights text in text box
onAbort	user stops page loading
onError	script encounters error

Different HTML entities accept different event handlers, e.g. onMouseOver applies only to "A HREF=" tags.

Newer versions of JavasScript add more events.
