Emacs is aweseome but sometimes it feels it's too smart for its own good. You may feel you learned everything there's to know about a function and then someone tells you to try a prefix argument and suddenly it does something you never knew about.
For example - you can jump to Magit without opening a project, by calling
magit-status with 2 prefix arguments (it will prompt you with a "choose directory" dialog) - I just learned that
So my question is: Is it possible to build a list of functions that take prefix arguments and for each row grab the description (maybe from
describe-function) that explains what calling the function with a prefix would do?
