With this add-on, you can create mappings between matched terms (words or sequences of words) and their suggested replacements. The incorrect terms that you will configure will be highlighted in the Author visual editing mode.
You can right-click the highlights to access various actions allowing you to replace each individual highlight with suggestions or to apply the same suggestion in multiple places in the opened document.
