How to get Esc as a keyCode

When you need the keyCode of any key, just write a short program with a key event, and within it, a call to println(keyCode);

Unfortunately, it seems that the canvas window on Khan Academy does not consider the escape key. There is a built in variable for the escape keyCode value (27) called ESC, but there is no point to using it. Try using E (keyCode 69) instead.
