The Announcements tool allows for the delivery of messages to the entire class, to groups, or to specific sections within the class.  Participants will see the Announcement message displayed in the Announcements area of their Home area, as well as within the course itself.  These messages can be set to show immediately, or to show during specific dates.  Email notifications can be sent to alert participants of the Announcement message.

You can use the Accessibility Checker to inspect the accessibility level of content created in the Rich-Text Editor and immediately solve any issues that are found.

The Accessibility Checker presents issues with each item in the text box one at a time.  For many issues, the Accessibility Checker gives you a Quick fix option.  If a Quick fix is not available, the checker will describe what needs to be done to fix the issue.

Organizing your page with helpful titles and headings creates an outline that helps your audience access the most important information more quickly and easily.

Assistive technology users rely heavily on page titles and headings to navigate complex content. Structuring complex content will help all users parse it as well.  Headings allow users to jump from one part of a document to another, without using a mouse.  Screen readers will interpret headings for those who use them.

Note that for this reason, you should not use headings for typographical effects.  If you need to increase or decrease the font size of large blocks of text, please use the Normal Paragraph Format and select a new Font size from the Size menu, or use Styles.
