+&lt;blockquote&gt;
+&lt;ul&gt;
+&lt;li&gt;A buffer is the in-memory text of a file.&lt;&#x2F;li&gt;
+&lt;li&gt;A window is a viewport on a buffer.&lt;&#x2F;li&gt;
+&lt;li&gt;A tab page is a collection of windows.&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;blockquote&gt;
+&lt;ul&gt;
+&lt;li&gt;&lt;kbd&gt;:e&lt;&#x2F;kbd&gt; refreshes the current buffer (&lt;code&gt;:e&lt;&#x2F;code&gt; is short for &lt;code&gt;:edit&lt;&#x2F;code&gt;)&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:e filename&lt;&#x2F;kbd&gt; open a particular file by its path, in the same window&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:e #&lt;&#x2F;kbd&gt; switch back to the previous buffer, won&#x27;t work if that buffer is not named&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;Ctrl&lt;&#x2F;kbd&gt;+&lt;kbd&gt;6&lt;&#x2F;kbd&gt; switch back to the previous buffer, works even if that buffer is not named
+&lt;ul&gt;
+&lt;li&gt;&lt;kbd&gt;Ctrl&lt;&#x2F;kbd&gt;+&lt;kbd&gt;^&lt;&#x2F;kbd&gt; can also be used&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:e #1&lt;&#x2F;kbd&gt; open the first buffer, and so on&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:buffers&lt;&#x2F;kbd&gt; show all buffers
+&lt;ul&gt;
+&lt;li&gt;&lt;kbd&gt;:ls&lt;&#x2F;kbd&gt; or &lt;kbd&gt;:files&lt;&#x2F;kbd&gt; can also be used&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:bn&lt;&#x2F;kbd&gt; open the next file in the buffer list (&lt;code&gt;:bn&lt;&#x2F;code&gt; is short for &lt;code&gt;:bnext&lt;&#x2F;code&gt;)
+&lt;ul&gt;
+&lt;li&gt;opens the first buffer if you are on the last buffer&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;li&gt;&lt;kbd&gt;:bp&lt;&#x2F;kbd&gt; open the previous file in the buffer list (&lt;code&gt;:bp&lt;&#x2F;code&gt; is short for &lt;code&gt;:bprevious&lt;&#x2F;code&gt;)
+&lt;ul&gt;
+&lt;li&gt;opens the last buffer if you are on the first buffer&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;&#x2F;li&gt;
+&lt;&#x2F;ul&gt;
+&lt;p&gt;&lt;img src=&quot;&#x2F;images&#x2F;info.svg&quot; alt=&quot;info&quot; &#x2F;&gt; Use &lt;kbd&gt;:set hidden&lt;&#x2F;kbd&gt; if you want to switch to another buffer even if there are unsaved changes in the current buffer. Instead of this setting, you can also use &lt;kbd&gt;:hide edit filename&lt;&#x2F;kbd&gt; to hide the current unsaved buffer. You&#x27;ll still get an error if you try to quit Vim without saving such buffers, unless you use the &lt;code&gt;!&lt;&#x2F;code&gt; modifier.&lt;&#x2F;p&gt;
