Sometimes the 54argument acts as a repeat count, other times it is the <i>sign</i> of the 55argument that is significant. If you pass a negative argument to a 56command which normally acts in a forward direction, that command will 57act in a backward direction. For example, to kill text back to the 58start of the line, you might type ‘<samp><span class="samp">M-- C-k</span></samp>’. 59 60 <p>The general way to pass numeric arguments to a command is to type meta 61digits before the command. If the first `digit' typed is a minus 62sign (‘<samp><span class="samp">-</span></samp>’), then the sign of the argument will be negative. Once 63you have typed one meta digit to get the argument started, you can type 64the remainder of the digits, and then the command. For example, to give 65the <kbd>C-d</kbd> command an argument of 10, you could type ‘<samp><span class="samp">M-1 0 C-d</span></samp>’, 66which will delete the next ten characters on the input line. 67 68 </body></html> 69 70
