== Description ==

Type complex math expressions easily into your wordpress page using MathQuill (http://mathquill.com/). This plugin adds a new block editor called 'Direct math input' in the 'widgets' category.

Math expressions are saved in LaTeX format and rendered by MathQuill during pageview.

= Usage =

After installing, a new block editor called 'Direct math input' will be available. Each block contains a MathQuill instance 
where you can edit math right on your page.

When the math editor is focused, you can enter math symbols using your keyboard or via copy/paste.
See the http://mathquill.com/ homepage for a visual demonstration of how to input math. 

Some common keyboard shortcuts are as follows:

| Key | Action                                                                                                                                |
|-----|---------------------------------------------------------------------------------------------------------------------------------------|
| /   | Enter a new fraction, with focusable input areas for numerator and denominator.                                                       |
| ^   | Enter a new superscript, e.g. to add an exponent                                                                                      |
