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).
To try out the velcro tooltip for this menu, reload 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.
