Techniques and systems for facilitating contextual information lookup and navigation are presented. Contextually relevant information can be presented without requiring a user to switch context or craft a search query. From within an application in which a user may consume or create content, a user may indicate text for further exploration. The application can receive the indication of an initial text selection, determine the intended selection and provide contextual search results to the user. In some implementations, the initial selection and a selection context (that includes at least some of the text surrounding the initial selection) is sent to a contextual search service which provides the intended selection and contextual search results based on the initial selection and selection context. In other implementations, text may be suggested by the contextual search service for selection from within the application.
