Mathematica Typesetting Shortcuts
by Paul Nylander, bugman123.com

Here is a Mathematica notebook that summarizes some convenient Mathematica typesetting shortcuts. You can type equations quite quickly in Mathematica once you know these shortcuts. I use these shortcuts to type my class notes in Mathematica.

For example, if you hold down the control key while typing the ^ key then it goes into superscript. For subscript you do the same thing using the underscore key. For square root you hold down the control key and type 2. For the Greek letter alpha you type the escape key followed by the letter a and then type the escape key again. There are also shortcuts for stacked fractions, integrals, sums, etc.
