we have just released the “Share Text” plugin.
This plugin allows you to make a text within your webpage shareable just by highlighting the text. The highlighted portion of the text can then be shared via email, twitter, linkedin and optionally facebook (if you have a facebook app id). The plugin fetches the highlighted text, as well as the page title and the page url to share.
Note: this plugin does not work on mobile devices.
Have a great day!
