CM Tooltip Plugin Glossary

The CM Tooltip is a plug-in for WP that enables you to parse pages or posts that are used for showing defined glossary words or phrases. Generates an index page that contains the definition of the words used, synonyms and definitions from the Merriam-Webster dictionary or Wikipedia encyclopedia. When enabled, the plug-in displays an infotip that contains the definition of the highlighted word or phrase when the cursor hover-over the text.
