This Epiphany extension uses the Deskbar's shortcuts for the browser's
``smart bookmarks'', or searches, so that, if you have the Wikipedia
search bookmarked, and you have configured Deskbar properly, you can
type ``wp foo'' in Epiphany's location bar to go to
http://en.wikipedia.org/wiki/Special:Search?search=%foo

To install, move the .js and .ephy-extension files into
~/.gnome2/epiphany/extensions/ and then, from Epiphany's menu, go to
Tools -> Extensions to enable it.

You can configure the shortcuts from Epiphany's Edit -> Bookmark
Shortcuts menu.  Alternatively, right-click on Deskbar's icon, choose
Preferences and from the ``Web Searches (Epiphany)'' extension, click
the ``More...''  button.  That, or just edit Deskbar's list of search
shortcuts (it's a text file):
~/.gnome2/deskbar-applet/search-bookmarks-shortcuts.txt

Note that this is an Epiphany extension, not a Deskbar extension.
Deskbar comes out-of-the-box with this behavior.

This extension was originally written by Nigel Tao.  It was ported to be
a ``Seed'' Javascript extension by Iain Nicol, to get it to work with
versions of Epiphany greater than 2.28.  However, to avoid crashes when
using this extension you should use Epiphany 2.29.3 or later, and Seed
2.29.5 or later.
