  71. 

  72. <p>You can pass numeric arguments to Readline commands.  Sometimes the

  73. argument acts as a repeat count, other times it is the <i>sign</i> of the

  74. argument that is significant.  If you pass a negative argument to a

  75. command which normally acts in a forward direction, that command will

  76. act in a backward direction.  For example, to kill text back to the

  77. start of the line, you might type &lsquo;<samp>M-- C-k</samp>&rsquo;.

  78. </p>

  79. <p>The general way to pass numeric arguments to a command is to type meta

  80. digits before the command.  If the first &lsquo;digit&rsquo; typed is a minus

  81. sign (&lsquo;<samp>-</samp>&rsquo;), then the sign of the argument will be negative.  Once

  82. you have typed one meta digit to get the argument started, you can type

  83. the remainder of the digits, and then the command.  For example, to give

  84. the <kbd>C-d</kbd> command an argument of 10, you could type &lsquo;<samp>M-1 0 C-d</samp>&rsquo;,

  85. which will delete the next ten characters on the input line.
