+&lt;ul&gt;
+&lt;li&gt;&lt;kbd&gt;:!ls&lt;&#x2F;kbd&gt; execute the given shell command and display output
+&lt;ul&gt;
+&lt;li&gt;the results are displayed as part of an expanded Command-line area, doesn&#x27;t change contents of the file&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:.!date&lt;&#x2F;kbd&gt; replace the current line with the output of the given command
+&lt;ul&gt;
+&lt;li&gt;pressing &lt;kbd&gt;!!&lt;&#x2F;kbd&gt; in Normal mode will also result in &lt;kbd&gt;:.!&lt;&#x2F;kbd&gt;&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;code&gt;!&lt;&#x2F;code&gt; waits for motion similar to &lt;code&gt;d&lt;&#x2F;code&gt; and &lt;code&gt;y&lt;&#x2F;code&gt; commands, &lt;kbd&gt;!G&lt;&#x2F;kbd&gt; will give &lt;kbd&gt;:.,$!&lt;&#x2F;kbd&gt;&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:%!sort&lt;&#x2F;kbd&gt; sort all the lines
+&lt;ul&gt;
+&lt;li&gt;recall that &lt;code&gt;%&lt;&#x2F;code&gt; is a shortcut for the range &lt;code&gt;1,$&lt;&#x2F;code&gt;&lt;&#x2F;li&gt;
+&lt;li&gt;note that this executes an external command, not the built-in &lt;code&gt;:sort&lt;&#x2F;code&gt; command&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:3,8!sort&lt;&#x2F;kbd&gt; sort only lines &lt;code&gt;3&lt;&#x2F;code&gt; to &lt;code&gt;8&lt;&#x2F;code&gt;&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:r!date&lt;&#x2F;kbd&gt; insert output of the given command below the current line&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:r report.log&lt;&#x2F;kbd&gt; insert contents of the given file below the current line
+&lt;ul&gt;
+&lt;li&gt;Note that &lt;code&gt;!&lt;&#x2F;code&gt; is not used here since there is no shell command&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:.!grep &#x27;^Help &#x27; %&lt;&#x2F;kbd&gt; replace the current line with all the lines starting with &lt;code&gt;Help&lt;&#x2F;code&gt; in the current file
