75
76<p><em>Killing</em> text means to delete the text from the line, but to save
77it away for later use, usually by <em>yanking</em> (re-inserting)
78it back into the line.
79(&lsquo;Cut&rsquo; and &lsquo;paste&rsquo; are more recent jargon for &lsquo;kill&rsquo; and &lsquo;yank&rsquo;.)
80</p>
81<p>If the description for a command says that it &lsquo;kills&rsquo; text, then you can
82be sure that you can get the text back in a different (or the same)
83place later.
84</p>
85<p>When you use a kill command, the text is saved in a <em>kill-ring</em>.
86Any number of consecutive kills save all of the killed text together, so
87that when you yank it back, you get it all.  The kill
88ring is not line specific; the text that you killed on a previously
89typed line is available to be yanked back later, when you are typing
90another line.
91<a name="index-kill-ring"></a>
92</p>
93<p>Here is the list of commands for killing text.
94</p>
95<dl compact="compact">
96<dt><kbd>C-k</kbd></dt>
97<dd><p>Kill the text from the current cursor position to the end of the line.
98</p>
99</dd>
100<dt><kbd>M-d</kbd></dt>
101<dd><p>Kill from the cursor to the end of the current word, or, if between
102words, to the end of the next word.
103Word boundaries are the same as those used by <kbd>M-f</kbd>.
104</p>
105</dd>
106<dt><kbd>M-<span class="key">DEL</span></kbd></dt>
107<dd><p>Kill from the cursor the start of the current word, or, if between
108words, to the start of the previous word.
109Word boundaries are the same as those used by <kbd>M-b</kbd>.
110</p>
111</dd>
112<dt><kbd>C-w</kbd></dt>
113<dd><p>Kill from the cursor to the previous whitespace.  This is different than
114<kbd>M-<span class="key">DEL</span></kbd> because the word boundaries differ.
115</p>
116</dd>
117</dl>
118
119<p>Here is how to <em>yank</em> the text back into the line.  Yanking
120means to copy the most-recently-killed text from the kill buffer.
121</p>
122<dl compact="compact">
123<dt><kbd>C-y</kbd></dt>
124<dd><p>Yank the most recently killed text back into the buffer at the cursor.
125</p>
126</dd>
127<dt><kbd>M-y</kbd></dt>
128<dd><p>Rotate the kill-ring, and yank the new top.  You can only do this if
129the prior command is <kbd>C-y</kbd> or <kbd>M-y</kbd>.
130</p></dd>
131</dl>
