右键先生-搜狗搜索 is a Chrome add-on developed by Browser Helper. It adds the functionality of searching text using Sogou search engine to the right-click menu. Unlike other comprehensive right-click extensions, this add-on is focused solely on Sogou search, making it more suitable for users who frequently use Sogou.

With this add-on, you can easily search for selected text by simply right-clicking and selecting the search option from the top-level menu. The add-on is developed using Event Pages mode, which means it doesn't consume memory when not in use and only uses memory when the right-click search is triggered.

One of the advantages of this add-on is its improved user experience. Unlike comprehensive right-click extensions that often bury the search option in submenus, this add-on places the search button directly in the top-level menu. This allows for quick and convenient access to Sogou search, especially for users who frequently use it.

Please note that this add-on does not currently support image search, as the image search functionality of Sogou is limited.
