Using a text 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.
If more than one text editor is enabled, users can select their preferred editor via their preferences page in the user menu (top right).

Image drag and drop
If your browser allows it (and if it does, you will see a message at the top of your screen when the editing is on) you can add images into the Atto editor simply by dragging them from your computer:
Text typed into the Atto editor is automatically saved if you leave the page. The default of 60 seconds may be changed by the administrator in Site administration>Plugins>Text editors>Atto HTML editor>Atto toolbar settings. If the user accidentally closes the tab or otherwise leaves the form without submitting, the text in the editor will be restored next time he opens the page. To discard a restored draft, the user needs to cancel the form or press the "Undo" button in the editor.
One of the tools available in the text editor is an automated accessibility checker which checks for some common errors in the text. These are usually things in the way the text is constructed that can prevent all users from having equal access to information and functionality. The list of problems that the accessibility checker looks for is:
- Images with missing or empty alt text (unless they have the presentation role)
- Contrast of font colour and background colour meets WCAG AA guidelines
- Long blocks of text are sufficiently broken up into headings
- All tables require captions
- Tables should not contain merged cells as they are difficult to navigate with screen readers
- All tables should contain row or column headers
Screen readers basically treat a content editable region like a text box - which is wrong, because it can contain images, links and more.
The screen reader helper provides additional information about the currently selected text (e.g. is it bold), as well as a listing of any images or links in the text.
If either the MathJax or the TeX notation filters are enabled (in Administration > Site administration > Plugins > Filters > Manage filters) then an equation editor button is provided in the toolbar for launching the equation editor.
In Moodle 3.0 onwards, extra buttons are provided for square roots, fractions and vectors.
If the administrator has enabled the extra settings for the Atto table editor (see below) then border styling, sizing and colours are available when creating a table:

- Word count quick guide - Word count is a plugin for the Atto text editor which is used to create content within Moodle. This plugin enables the author of text, such as a student, to check how many words and letters are in a piece of text.
