Wikidata Search — Upollo

Created especially for Wikipedia editors, this add-on makes it easy to find data items on http://www.wikidata.org related to your article without having to laboriously open a new tab, then open wikidata, then type in a search term ... simply highlight some relevant text in your editing page (either in the editing box or elsewhere in the page), right click and select "Quickly lookup the highlighted text on Wikidata". A new tab will open in wikidata.org with your search results.
