Atto editor

The text editor (sometimes referred to as the 'HTML editor' has many icons to assist the user in entering content. Many of these icons and functions should be familiar to anyone who uses a word processor. Some examples of where you will see the text editor include: Editing Section headings, description of an activity, writing an answer to a quiz question or editing the content of many blocks.

The default text editor in Moodle is the Atto editor, built specifically for Moodle. There is also a version of the TinyMCE editor and a plain text editor.

Text editors can be enabled, disabled or a different one set to default from Administration > Site administration > Plugins > Text editors > Manage editors. The order of priority may also be specified here.

An individual user can select an editor in their profile from Administration > My Profile settings > Edit profile.
