Word 2010 Equation Shortcuts

I didn't like Word 2007's equation editor at first, because unlike the old one, to input x^2 you had to click on the superscript box before typing x, which I kept forgetting and seemed unnatural (it's like reading "superscript x 2"). However, I found out Word seems to use the "Unicode Nearly Plain-Text Encoding of Mathematics" standard, which means equations are stored and can be entered as a string of text, which could make entering equations very easy!

Most of my ideas came from Linear format equations and Math AutoCorrect in Word 2010.

There are lot of other functions supported, these are the types I'm using now.
