When moving the cursor to an underlined word in some pages, a large
rectangle will appear at its right upper corner or somewhere around,
displaying relevant information. When the cursor moves away, the
rectangle disappears. This is a convenient and useful effect, and I
like to learn the skills.

If anyone knows where to go, such as online tutorial or books, please
share the information with me. Thanks.
