Readline Arguments
You can pass numeric arguments to Readline commands. Sometimes the argument
acts as a repeat count, other times it is the sign of the argument that is significant. If you pass a negative argument to a
command which normally acts in a forward direction, that command will act in a
backward direction. For example, to kill text back to the start of the line, you
might use M-- C-K.
The general way to pass numeric arguments to a command is to type meta digits
before the command. If the first ‘digit’ you type is a minus sign (-), then the
sign of the argument will be negative. Once you have typed one meta digit to
get the argument started, you can type the remainder of the digits, and then the
command. For example, to give the
C-D command an argument of 10, you could use the keystroke sequence, M-1, 0, C-D.
