The bookmarklet is an essential part of Radio3.
To install it, drag the "R3" link below into the toolbar of your browser.
When you're on a page you want to link to, click the bookmarklet. Radio3 will open with the fields of the dialog filled with the title of the page. The link is included, along with a shortened version for Twitter posts.
The toolbar works differently in each of the browsers. If you have questions, post them here and we'll try to get the answer.
