| |
| <dl> |
| <dt><code>delete-char (C-d)</code><a name="index-delete_002dchar-_0028C_002dd_0029-2239"></a><dd>Delete the character at point. If point is at the |
| beginning of the line, there are no characters in the line, and |
| the last character typed was not bound to <code>delete-char</code>, then |
| return <span class="sc">eof</span>. |
| |
| <br><dt><code>backward-delete-char (Rubout)</code><a name="index-backward_002ddelete_002dchar-_0028Rubout_0029-2240"></a><dd>Delete the character behind the cursor. A numeric argument means |
| to kill the characters instead of deleting them. |
| |
| <br><dt><code>forward-backward-delete-char ()</code><a name="index-forward_002dbackward_002ddelete_002dchar-_0028_0029-2241"></a><dd>Delete the character under the cursor, unless the cursor is at the |
| end of the line, in which case the character behind the cursor is |
| deleted. By default, this is not bound to a key. |
| |
| <br><dt><code>quoted-insert (C-q or C-v)</code><a name="index-quoted_002dinsert-_0028C_002dq-or-C_002dv_0029-2242"></a><dd>Add the next character typed to the line verbatim. This is |
| how to insert key sequences like <kbd>C-q</kbd>, for example. |
| |
| <br><dt><code>tab-insert (M-<TAB>)</code><dd>Insert a tab character. |
| |
| <br><dt><code>self-insert (a, b, A, 1, !, ...)</code><a name="index-self_002dinsert-_0028a_002c-b_002c-A_002c-1_002c-_0021_002c-_0040dots_007b_007d_0029-2243"></a><dd>Insert yourself. |
| |
| <br><dt><code>transpose-chars (C-t)</code><a name="index-transpose_002dchars-_0028C_002dt_0029-2244"></a><dd>Drag the character before the cursor forward over |
| the character at the cursor, moving the |
| cursor forward as well. If the insertion point |
| is at the end of the line, then this |
| transposes the last two characters of the line. |
| Negative arguments have no effect. |
| |
| <br><dt><code>transpose-words (M-t)</code><a name="index-transpose_002dwords-_0028M_002dt_0029-2245"></a><dd>Drag the word before point past the word after point, |
| moving point past that word as well. |
| If the insertion point is at the end of the line, this transposes |
| the last two words on the line. |
| |
| <br><dt><code>upcase-word (M-u)</code><a name="index-upcase_002dword-_0028M_002du_0029-2246"></a><dd>Uppercase the current (or following) word. With a negative argument, |
| uppercase the previous word, but do not move the cursor. |
| |
| <br><dt><code>downcase-word (M-l)</code><a name="index-downcase_002dword-_0028M_002dl_0029-2247"></a><dd>Lowercase the current (or following) word. With a negative argument, |
| lowercase the previous word, but do not move the cursor. |
| |
| <br><dt><code>capitalize-word (M-c)</code><a name="index-capitalize_002dword-_0028M_002dc_0029-2248"></a><dd>Capitalize the current (or following) word. With a negative argument, |
| capitalize the previous word, but do not move the cursor. |
| |
| <br><dt><code>overwrite-mode ()</code><a name="index-overwrite_002dmode-_0028_0029-2249"></a><dd>Toggle overwrite mode. With an explicit positive numeric argument, |
| switches to overwrite mode. With an explicit non-positive numeric |
| argument, switches to insert mode. This command affects only |
| <code>emacs</code> mode; <code>vi</code> mode does overwrite differently. |
| Each call to <code>readline()</code> starts in insert mode. |
| |
| <p>In overwrite mode, characters bound to <code>self-insert</code> replace |
| the text at point rather than pushing the text to the right. |
| Characters bound to <code>backward-delete-char</code> replace the character |
| before point with a space. |
| |
| <p>By default, this command is unbound. |
