| <dt><code>digit-argument (</code><kbd>M-0</kbd><code>, </code><kbd>M-1</kbd><code>, ... </code><kbd>M--</kbd><code>)</code><a name="index-digit_002dargument-_0028_0040kbd_007bM_002d0_007d_002c-_0040kbd_007bM_002d1_007d_002c-_0040dots_007b_007d-_0040kbd_007bM_002d_002d_007d_0029-2265"></a><dd>Add this digit to the argument already accumulating, or start a new |
| argument. <kbd>M--</kbd> starts a negative argument. |
| |
| <br><dt><code>universal-argument ()</code><a name="index-universal_002dargument-_0028_0029-2266"></a><dd>This is another way to specify an argument. |
| If this command is followed by one or more digits, optionally with a |
| leading minus sign, those digits define the argument. |
| If the command is followed by digits, executing <code>universal-argument</code> |
| again ends the numeric argument, but is otherwise ignored. |
| As a special case, if this command is immediately followed by a |
| character that is neither a digit or minus sign, the argument count |
| for the next command is multiplied by four. |
| The argument count is initially one, so executing this function the |
| first time makes the argument count four, a second time makes the |
| argument count sixteen, and so on. |
| By default, this is not bound to a key. |
