Unfortunately I can't remember where all these came from, so I'm just going to paste the code in here for most of them. I've also left out a lot of bookmarklets whose functions are available in the Web Developer extension.
- Bloglines Citations - find links from other pages
- Tasty - show tags on del.icio.us [link]
- Waypath It! - find similar pages [link]
- Playr - play linked media files [link]
- Mouseover DOM Inspector (external link) - show DOM attributes for parts of the current page
- Javascript shell (external link) - a command-line Javascript interface
- Remember Password - allows browsers to remember passwords for forms with autocomplete="off" [link]
- Cite - quote selected text with attributes
- Colour Generated Source - show the source code for the current page [link]
- Translate - send the current page through Google's translator
- TinyURL - create a short URL
- Webjay - add a media file to a Webjay playlist
- AllAbstracts - send PubMed links to HubMed
Comments
All fields are optional, email address will not be shown; no HTML, URLs are automatically hyperlinked.

Since the PubMed->HubMed code often gives you duplicate PMIDs it would be nice if HubMed automatically cleared duplicates from its display.
Yes, it used to do that but something changed recently - I'll have to fix it.
Hello,
I am new to the world of Bookmarklets but love them so decided to build four. I'd love your comments on them.

Here is a brief description of the 4 Bookmarklets...
Save to BlinkBits - Click the "Save to BlinkBits" bookmarklet while surfing any site to save and share text, pictures, urls, your thoughts and more.
Blink - Highlight any word or phrase on any site and then click the "Blink" bookmarklet to Discover Bio, Pictures, News, Videos and more from 11.2 billion sources.
Get RSS Feed - Highlight any word or phrase on any page and then click the "Get RSS Feed" bookmarklet to get (or create) a RSS Feed with Bio, Pictures, News, Videos and more from 11.2 billion sources.
Wikr - Highlight any word or phrase on any site and then click the "Wikr" bookmarklet to get a mash of the Wikipedia Article and Flickr Pictures.
Any thoughts on them would be greatly appreciated...
