Twitter users can drag the "Share on Twitter" bookmarket to their browser's bookmarks bar -- all major browsers are supported.
A click of the button opens a new window with the web page title and shortened URL pre-populated in the customizable tweet field. Twitter is using its own t.co URL shortener to shorten the links users share on Twitter via the bookmarklet.
The bookmarklet addition is a minor one. For years, third-party applications and clients have offered bookmarklets for faster sharing. Still, the update is convenient for those who want to share web pages not already using the official Tweet Button and who prefer to use Twitter.com rather than a client like Tweetdeck.
