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.
