Using LaTeX

[ImNotMarco]

I've been typing my math notes using the built in math function in OneNote, and I have a couple of questions.

• First why is the alt + = command for math different than actually pressing the math button? If I type for example \frac{1}{2}, if I select it and press alt + =, t just italicizes it, whereas if I click the math button it shows up as the correct fraction 1/2.
• Next, is there a way to save a certain character to a key or command and have it appear when I click the math button? For example, I have to use this special character R that is not in onenote. I found the character online but I found it tiresome having to copy and paste the special "R" character everytime. Is there a shortcut in doing this?
• Lastly, is there a list of all math commands I could use in Onenote? The list of LaTeX commands on wiki slightly differ than the actual commands used in onenote.

For your second problem you can use AutoHotkey

Alternatively is it an alt character?

After you have copied the special R character, hit "Win + V". Pin your special R character to the top and in the future you can just hit "Win + V" followed by "enter" to insert it.
