Remarks

An Accelerator can optionally provide a HTML preview that is displayed when the user hovers over an Accelerator in the context menu. This can be useful to quickly obtain a map, in-place definition or translation, and even ratings or links to related content.

The preview window is limited to 320 x 240 (WH) on a 96 dots per inch (dpi) display. All content outside of the region is cut off. Content with scrollbars is not recommended. The preview window is suitable for light-weight user interaction; provide links to send the user to view the full Web page for more information.

Examples

The following Accelerator snippet uses an optional os:preview element to display the definition of the selected word when the user hovers over the Accelerator menu item.

<os:activity category="define">
  <os:activityAction context="selection" >
    <os:preview action= "http://www.example.com/preview.php?word={selection}"/>
    <os:execute method="get" action="http://www.example.com/define.php">
      <os:parameter name="word" value="{selection}" type="text" /> 
    </os:execute>
  </os:activityAction>
</os:activity>
