Testing bookmarklets

What are bookmarklets?

A bookmarklet is a web browser bookmark with JavaScript commands that add new features. These small JavaScript snippets are stored as a bookmark URL and executed when clicked.

How do you use them?

Drag the bookmarklet links below into your browser’s Bookmarks Bar.
When you are on the page you want to test, click on the bookmarklet.
