This is not XWiki specific, but a CSS feature. In your stated example, the
CSS code is:
<style>
.wikiexternallink {
background: url("[...]/externallinkicon.gif") no-repeat scroll right
center transparent;
padding-right: 12px;
}
</style>

i want to mark external links in my wiki like it's
done here:
http://www.xwiki.org/xwiki/bin/view/Main/ExternalLinks with a symbol after
the
link.
How can i do that?
