Navigation popups
The Navigation popups wikitool allows easier access to several Wikipedia features as "popups" which appear when you hover the mouse over links. With this useful tool, when you hover your mouse cursor over a wikilink you can see a preview of the article or image; plus you can activate convenient functions such as going directly to the talk, edit, or history pages. In order to use navigation popups you must be logged in under your own user account and install some JavaScript onto a subpage of your userpage. Full instructions are in the Navigation popups article.
