This question already has an answer here:
Another question asks whether there is a keyboard shortcut for evaluating a notebook. The answer is yes. The quickest way that someone came up with was pressing Alt+V and then O, but the question did not ask for which way was fastest.
My question is different. I am asking whether there is a way that is faster than typing Alt+V and then O.
This might be another key combination, or it might be making a button that can be put at the top of the notebook. Getting a button which appears at the top of the code when the program is opened, and that I can click on to execute the whole thing, would be ideal.
