- Strictly speaking, a numeric argument is one type of the more general concept
- of prefix argument. Prefix arguments come in two flavors: numeric and raw.
- The gory details can be found in the GNU Emacs Lisp Reference Manual, section
- 18.7.
-
- The GNU Emacs Manual, on the other hand, is a users manual that doesn't try to
- go into all the Emacs Lisp language subtleties. Doing so would most likely
- confuse a new user. So section 4.9 in the Emacs Manual is called Numeric
- Arguments, even though it also discusses the use of C-u, which is bound to the
- universal-argument command.
-
- For the GNU Emacs user who is NOT an Emacs Lisp programmer, the phrase
- "numeric argument" conveys some meaning immediately while the phrase "prefix
- argument" requires some explanation.
