Dictionary Lookup Chrome Extension

 This extension that allows you to quickly look up definitions of words and phrases in a clean inline box. The definitions come from Wiktionary, but have been preprocessed to reduce formatting and provide faster lookup. Hold a modifier key (Alt on Windows, Command on Mac, Ctrl on Linux) and double-click or select any word to look it up - an inline box will open to the dictionary entry of that word, usually including examples, audio pronunciation and synonyms.

You can also lookup manually-entered queries using a shortcut which displays a small query form.

NOTES:
1. After installing, pages already open will not work for looking up - just refresh them and itll be solved.
2. The Chrome Extensions Gallery pages dont allow lookup (or any on-page extensions) for security reasons. 
3. This extension does not add a toolbar icon.
