The 'Поиск по выделенному тексту' extension enhances the browsing experience by enabling quick searches for highlighted text across various search engines, including Google, Bing, and DuckDuckGo. Users can highlight any text on a webpage and initiate a search through keyboard shortcuts or the context menu, streamlining their information retrieval process. This tool is particularly useful for users who frequently need to look up definitions, references, or additional information without leaving their current page.

Moreover, the extension allows users to create an unlimited number of quick links by entering a name and specifying the search URL. The highlighted text is automatically appended to the URL, making the search process even more efficient. The first four links in the quick access list come with dedicated keyboard shortcuts, enhancing usability and speed. Overall, this extension serves as a valuable tool for anyone looking to optimize their web browsing and research capabilities.
