# Rich Text

Use **Rich Text** for formatted explanations, examples, lists, and notes. Formatting is applied with the editor toolbar; typing Markdown punctuation is not the same as applying a toolbar format.

## Format an explanation

1. Add a Rich Text field to your template, usually on **Back** or **Note**.
2. Open a card and tap the field to enter text.
3. Select the words you want to format, then use the keyboard toolbar.
4. Preview the field and save the card.

For example, write a short definition, make its key term bold, then add a bulleted list of two examples. Keep the essential answer in a separate field if the explanation would reveal too much during recall.

## Toolbar controls

| Control                                | Use                                                |
| -------------------------------------- | -------------------------------------------------- |
| Text size                              | Choose a size from **Text Sizes**                  |
| Bold, italic, underline, strikethrough | Emphasize selected text                            |
| List/format control                    | Add numbered or bulleted lists; adjust indentation |
| Text color                             | Change the selected text's color                   |
| Highlight                              | Set a background highlight                         |
| Subscript and superscript              | Format characters above or below the baseline      |

The active toolbar control indicates formatting at the current selection. Formatting without a range selected affects text entered at that position.

## Choose Rich Text or another type

Use [TeX](https://docs.flashnerd.com/reference/fields/tex.md) for mathematical expressions that need proper typesetting, and [Code](https://docs.flashnerd.com/reference/fields/code.md) for syntax-highlighted programming examples. Rich Text is not a supported source for a TTS field reference; put the spoken wording in a [Text](https://docs.flashnerd.com/reference/fields/text.md) field if you need both rich formatting and speech.

Field visibility and template inheritance work as described in [Field settings](https://docs.flashnerd.com/guide/cards/field-settings.md).
