Sometimes the 74argument acts as a repeat count, other times it is the <i>sign</i> of the 75argument that is significant. If you pass a negative argument to a 76command which normally acts in a forward direction, that command will 77act in a backward direction. For example, to kill text back to the 78start of the line, you might type ‘<samp>M-- C-k</samp>’. 79</p> 80<p>The general way to pass numeric arguments to a command is to type meta 81digits before the command. If the first ‘digit’ typed is a minus 82sign (‘<samp>-</samp>’), then the sign of the argument will be negative. Once 83you have typed one meta digit to get the argument started, you can type 84the remainder of the digits, and then the command. For example, to give 85the <kbd>C-d</kbd> command an argument of 10, you could type ‘<samp>M-1 0 C-d</samp>’, 86which will delete the next ten characters on the input line. 87</p> 88 89 90 91</body> 92</html> 93
