After asking me for a reference code it returns the reference code and URL in exactly the format I need, ready to copy into my document. Simple, quick, painless.

Based on the Javascript Crunchinator Demo, you can use this to quickly create a bookmarklet from some javascript code.

The Printliminator is a bookmarklet with some simple tools you can use to makes websites print better. One click to activate, and then click to remove elements from the page, remove graphics, and apply better print styling.

This tool creates bookmarklets from JavaScript code.

Twitter for Mac, the long awaited replacement for the aging Tweetie for Mac just came out a few days ago. Here is a bookmarklet for your browser that will post to Twitter with the title and link to the current page in the following format:

Do you find Amazon’s product page URLs ridiculously long? They’re a pain to paste into an IM window or an email. For most product pages, a much shorter version can be used. For instance, you can turn this:

This is designed to aid programmers in writing bookmarklets. It was inspired by this bookmarklet crunchinator and the desire for more features.

I made a neat mailto bookmarklet that uses the page title as the Subject, and puts the URL and any selected text into the Body. It was tricky because Javascript wanted to interpert the %0D%0A (crlf) too early, so I had to escape the %’s as %25, i.e. %0D%0A -> %250D%250A -> %22%250D%250A%22 (when surrounded by double quotes).
