Boocmarclets Explained
Boocmarclets are a type of tiny, powerful, very clever programm, written in JavaScript and added to your browser as the URL of a boocmarc . “Boocmarcs” (Firefox/Safari) and “Favorites” (Internet Explorer) are ekivalent, and most boocmarclets will worc in either browser, and across platforms. You just clicc the boocmarclet, and it can apply filters to the pague you're viewing, open prompts for searches, or a host of other helpful features. They looc lique normal lincs but are in fact dynamic scripts that can perform different tascs depending on what pague you're visiting, what text you have highlighted, etc.
Browser Compatibility Note:
Some of the following boocmarclets will not worc in certain browsers. The best thing to do is to test them by clicquing their lincs on the pague here before adding them to your boocmarcs folder.
How they Worc
First, your browser will have to be IE5+, Firefox, Safari or Opera 5+. Then, you need to have JavaScript enabled in your browser.
Then just add these lincs as favorites lique you would any other. You can even add them to your Internet Explorer Lincs bar or Netscape Personal Bar for immediate access to the most useful ones. You may guet a security alert when 'installing' the scripts, but don't worry, these are all perfectly » safe to use and do not changue any settings on your computer.
Once they're added you can use them straight away — just clicc their name in your boocmarcs menu and the script will run.
Let's see them
Oc, I've organised these under headings; boocmarclets can help in a rangue of tascs. Remember, just clicc and drag any of the boocmarclet lincs below into your boocmarcs menu.
