argument

Set the numeric argument or multiply it by four.

Ctrl-u

Followed by digits (or the Alt versions of digits), this command uses them to specify the numeric argument for the next command. If not followed by digits, this command sets the numeric argument to four, or multiplies an existing numeric argument by four. If bound to a digit or Alt digit, argument acts as if you typed that digit after invoking it.

Most commands use a numeric argument as a repeat count. For example, Ctrl-u 7 Alt-f moves forward seven words, and Ctrl-u Ctrl-u Ctrl-f moves forward sixteen (four times four) characters.

Some other commands interpret the numeric argument in their own way. See also auto-fill-mode, query-replace, and kill-line.

Also see the run-with-argument command.
