After searching at length for a Joomla component that automatically adds links and tooltips to keywords in articles I couldn't find anything that suited my needs so I decided to develop the extension myself and learn a new skill at the same time.
Description
Autolinks is a free extension for Joomla 3 which takes the work out of keyword linking and lets you easily add tooltips to words or phrases of your choice. Using this extension is as easy as downloading it and installing it then adding new keywords with links and/or tool tip descriptions . You can choose to have both or just one or the other.
