Wysiwyg + CKEditor Screencast
Drupal website developers are often called upon to help website users easily format text when they create new pages or nodes. HTML is the preferred way to format text but users don't always have proficiency with the markup language and sometimes prefer to have an interface that formats their HTML language for them - not unlike the formatting buttons in Microsoft Word.
This screencast covers one method of adding easy HTML formatting to your Drupal website with the Wysiwyg module and the open source editor tool called CKEditor. To make the best use of this screencast, you should have basic knowledge of Drupal 7 site configuration including how to create content and edit content and how to install new modules.
