The equation editor in Google Docs is based on LaTeX syntax and recognizes similar shortcuts. You can type a backslash (\) followed by the name of a symbol and a space to insert that symbol. For example, when you type

        \alpha
    

, the Greek letter Alpha is inserted.

Google doesn't have a list of all the available shortcuts. If you want to take advantage of them, use these shortcuts instead of clicking each drop-down menu to access symbols.
