| <p>In order to enter characters into the line, simply type them. The typed |
| character appears where the cursor was, and then the cursor moves one |
| space to the right. If you mistype a character, you can use your |
| erase character to back up and delete the mistyped character. |
| </p> |
| <p>Sometimes you may mistype a character, and |
| not notice the error until you have typed several other characters. In |
| that case, you can type <kbd>C-b</kbd> to move the cursor to the left, and then |
| correct your mistake. Afterwards, you can move the cursor to the right |
| with <kbd>C-f</kbd>. |
| </p> |
| <p>When you add text in the middle of a line, you will notice that characters |
| to the right of the cursor are ‘pushed over’ to make room for the text |
| that you have inserted. Likewise, when you delete text behind the cursor, |
| characters to the right of the cursor are ‘pulled back’ to fill in the |
| blank space created by the removal of the text. A list of the bare |
| essentials for editing the text of an input line follows. |
| </p> |
| <dl compact="compact"> |
| <dt><kbd>C-b</kbd></dt> |
| <dd><p>Move back one character. |
| </p></dd> |
| <dt><kbd>C-f</kbd></dt> |
| <dd><p>Move forward one character. |
| </p></dd> |
| <dt><tt class="key">DEL</tt> or <tt class="key">Backspace</tt></dt> |
| <dd><p>Delete the character to the left of the cursor. |
| </p></dd> |
| <dt><kbd>C-d</kbd></dt> |
| <dd><p>Delete the character underneath the cursor. |
| </p></dd> |
| <dt>Printing characters<!-- /@w --></dt> |
| <dd><p>Insert the character into the line at the cursor. |
| </p></dd> |
| <dt><kbd>C-_</kbd> or <kbd>C-x C-u</kbd></dt> |
| <dd><p>Undo the last editing command. You can undo all the way back to an |
| empty line. |
| </p></dd> |
| </dl> |
| |
| <p>(Depending on your configuration, the <tt class="key">Backspace</tt> key be set to |
| delete the character to the left of the cursor and the <tt class="key">DEL</tt> key set |
| to delete the character underneath the cursor, like <kbd>C-d</kbd>, rather |
| than the character to the left of the cursor.) |
