Selection Search is a free Chrome extension developed by Pitmairen. It falls under the category of Browsers and is specifically listed as an Add-ons & Tools subcategory.

With Selection Search, users can conveniently search for any text they have selected. When a portion of text is selected, a left click on the selected text brings up a popup menu where users can choose a search engine to perform the search with.

In the options page, users have the ability to customize the appearance of the menu, specify the mouse button that activates the menu, select which search engines to display, and more.

Please note that upon installation, users will receive a warning that the extension has access to their data on all websites. This is necessary for the extension to function properly as the code for the popup menu needs to be added to every website.

Recent updates to the extension include the addition of new buttons for adding search engines, separators, and submenus at specific positions in the search engine list, the inclusion of a search-url variable for query string variables without encoding, and more.
