I am trying to use
C-h k to describe the function to which a key is bound. But when I use it with a key chord like
C-u C-e C-x it retrieves the documentation for
C-u before I can finish typing the chord. What is the correct way to describe this type of chord?
Prefix keys like C-u may be described in the function body. You should therefore ignore such prefix keys when using C-h k to describe a function.
