What is a bookmarklet?

A bookmarklet is a browser bookmark (or favorite) that "does something" when it is clicked on.

For example, Google Translation bookmarklet, when used will translate the current web page to the language of your choice.

"Get translations with a single click by adding one of the buttons below to your browser's toolbar. Then whenever you want to translate a webpage you're viewing, just click the button. You can translate any part of the page by selecting that part before you click.

To add a button, drag it from this page to your browser's toolbar"
