Patterns that activate on enter are still canceled with any modifier active. Props azaozz. Fixes #33382. Built from https://develop.svn.wordpress.org/trunk@33622 git-svn-id: http://core.svn.wordpress.org/trunk@33589 1a063a9b-81f0-0310-95a4-ce76da25c4cd

/**
|
|
* Text pattern plugin for TinyMCE
|
|
*
|
|
* @since 4.3.0
|
|
*
|
|
* 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.
