Since the version 2.2, the clipboard has been implemented into i4. Each search toolbar has two new buttons to add or remove selected elements from the list of clipped items. When an item is in clipboard a "clip" icon is visible inside element container. A new search named "Clipboard" is available to show current elements. A new configuration command is also available:

<menuItem name="ClipboardAdd" iconName="fa-plus-square" command="clipboard">

  <params>

   <add key="op" value="+"/>

  </params>

 </menuItem>

 <menuItem name="ClipboardDel" iconName="fa-minus-square" command="clipboard">

  <params>

   <add key="op" value="-"/>

  </params>

</menuItem>
