| <h4 class="subsection">31.2.4 Readline Arguments</h4> |
| |
| <p>You can pass numeric arguments to Readline commands. Sometimes the |
| argument acts as a repeat count, other times it is the <i>sign</i> 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 type ‘<samp><span class="samp">M-- C-k</span></samp>’. |
| |
| <p>The general way to pass numeric arguments to a command is to type meta |
| digits before the command. If the first `digit' typed is a minus |
| sign (‘<samp><span class="samp">-</span></samp>’), 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 <kbd>C-d</kbd> command an argument of 10, you could type ‘<samp><span class="samp">M-1 0 C-d</span></samp>’, |
| which will delete the next ten characters on the input line. |
