* Allows developers to add custom tooltips to the webpages. Tooltips are
* generated using the domTT_activate() function and customized by setting
* a handful of options.

<div class="main">
<p>This example thinks way outside the box, replacing the context menu with a custom tooltip. Right click on the page to see a custom context menu. (If you are on Opera 7 or Konqueror, use CTRL+click). Hold down control key to get a regular context menu (If you are on Opera 7 or Konqueror, get the context menu with a right click).</p>
<p>To try out the <em>velcro</em> tooltip for this menu, <a href="">reload (Right click)</a> the page with the 'type' option set to 'velcro'. Notice when you mouse out of the tip, it destroys itself. No need to click somewhere on the page to kill the menu.</p>
