Tools, part 2: Internal links and page histories
This article is a continuation of Tools, part 1, in a series meant to introduce readers to useful tools for editing. This time, we will be treating tools related to internal links (wikilinks), and the version histories of wiki pages.
Many tools consist of user scripts, JavaScript code running in your browser, that can be imported by adding importScript("User:Example/awesome script.js") to your skin.js page. Compatibility varies with skin and browser, with Internet Explorer being the most problematic. A more extensive script list is at Wikipedia:WikiProject User scripts/Scripts.
Various other tools are hosted on the Wikimedia Toolserver (currently provided by the German Wikimedia chapter) and can be accessed via a web interface. Some are also hosted on non-Wikimedia websites.
