What’s a bookmarklet? Well, the Bookmarklets.com home page describes them in this way:
Bookmarklets are simple tools that extend the surf and search capabilities of Firefox and Explorer web browsers.
Bookmarklets are free.
Bookmarklets allow you to:
* Modify the way you see someone else’s webpage.
* Extract data from a webpage.
* Search more quickly, and in ways not possible with a search engine.
* Navigate in new ways.
…and more. Over 150 bookmarklets are available.
Bookmarklets work on all platforms (Windows, Macintosh, Unix,…)
You do not have to download or install software to use Bookmarklets.
