What is a bookmarklet?
"A bookmarklet is an applet, a small computer application, stored as the URL of a bookmark in a web browser." It looks just like a normal bookmark.
In our case, the Highlighter bookmarklet allows you to highlight any page on-the-fly without having to copy & paste the page URL to www.awesomehighlighter.com.
Simply click on the bookmark whenever you want to start highlighting a page and the highlighter toolbar will appear.
You can read more about bookmarklets on Wikipedia here.
