"new" equation editor in word

Since circa 2010 you can do nice things with the Equation Editor  (even for Mac) in Word and Power Point. For instance my notes on genomic prediction. Note that this is NOT the horrible Equation Editor that you think:

But a new one which has LaTex-y kind of input, using Math Autocorrect:

which is based on this. It works nicely in PowerPoint too:

 So, I completely gave up using MathType.

However, there are no good resources for this nrew Equation Editor, and the web of Math Autocorrect is not very good.

I used this documentati to learn (although it is a bit outdated):
