Hitkey is a Chrome extension developed by Eiji Muroichi that enhances web surfing by allowing users to quickly search selected text on a webpage. With just a simple keystroke, users can open a new tab with the search results page based on the selected words. This extension supports up to 10 customizable keys for different search engines.

The default setting of Hitkey includes keys for popular search engines like Google, Google Maps, Wikipedia, Amazon, and Yelp. Users can easily configure their preferred search engines for each key.

It is important to note that Hitkey may not work on websites that already have keyboard interaction implemented or use frames or iframes. Additionally, if the user has other extensions installed that utilize keyboard events, Hitkey may not function properly.

To customize the settings, users can go to Preferences > Extension > Hitkey Option and paste a URL that includes "{query}" to create personalized search queries for different websites. This allows for a more tailored and efficient web surfing experience.

Overall, Hitkey is a valuable Chrome extension that provides fast and efficient web surfing capabilities by allowing users to quickly search selected text with just a keystroke. Its customizable features make it a versatile tool for users to personalize their web browsing experience.
