Thank you for choosing Telerik RadEditor for SharePoint!
RadEditor for Microsoft Office SharePoint Server extends the web content authoring environment of SharePoint 2007/2010 by providing cross-browser compatibility and support for the Apple Mac OS platform. In the default configuration, the product offers an almost identical functionality level as the integrated rich-text editor and can be used in the following scenarios:
