The Preview Button initially reads the page defaults and displays them; it changes according to your selected changes displaying those changes, with the exception of the Button Name and Button Caption. Cursor change options are generally only visible in Internet Explorer version 4 and up, although SOME IE emulations do support them. You can also manually change options in the generated code if you desire. If present, the underlined BOLD single character on a button (example 1) is the HTML accessKey. A single click on the keyboard of the accessKey plus the TriggerKey is the same as clicking the button. On a PC. the TriggerKey is generally ALT; on a Mac, it is generally CTRL. The term generally is used because there are exceptions; for one on either a PC or Mac, the Opera browser TriggerKey is SHIFT+ESC. NOTE: For several versions of HTML and XHTML, the accessKey was eliminated (officially termed deprecated). It is now supported again in HTML5, as of September 2009.
