|
* This plugin can automatically format text patterns as you type. It includes two patterns:

* - Unordered list (`* ` and `- `).
|
|
* - Ordered list (`1. ` and `1) `).
|
|
*
|
|
* If the transformation in unwanted, the user can undo the change by pressing backspace,
|
|
* using the undo shortcut, or the undo button in the toolbar.
