"For starters, GoldenDict supports a wide range of dictionary formats, including StarDict dictionaries, Babylon .BGL files, Dict dictionary files as well as ABBYY Lingvo source files and audio archives. In addition to that, GoldenDict supports MediaWiki-based references, which include both Wikipedia and Wiktionary. But that's not all. Since GoldenDict is based on the WebKit toolkit it can parse and display data from virtually any Web site, so you can use GoldenDict to look up words in many popular online references, as long as they support URL-based queries. GoldenDict's other comfort creatures include Scan Popup and global hotkeys. When the Scan Popup feature is enabled, GoldenDict pops up a dictionary article for the currently selected word, and you can use this functionality in any application."
