From the Hall: GmailThis!
GmailThis! is an easy way to make a Gmail email without visiting mail.google.com. Once you add the GmailThis! link to your browser’s toolbar, emailing will be a snap. Or rather, a click. Clicking GmailThis! creates a mini-interface to Gmail prepopulated with a link to the web page you are visiting, as well as any text you have highlighted on that page. Add additional text if you wish and then email or save as draft from within GmailThis! http://contrapants.org/blog/2005/07/gmailthis.html
