I'm following this Lisp tutorial, which provides you with a Lisp interpreter and Emacs to make setting stuff up easier. However, I want to change the font, and everything Google has given me involves putting some cryptic lisp commands in a file, or pressing some key combination, or giving it a long font name, and they're all pretty complicated.
Is there any way to simply open a font selection dialog or something like that? Or maybe a simple command to use? Keep in mind I'm a beginner.
