+<title>Saving your changes</title>
+
+<p>
+Once you've finished editing your files, you need to save each file you've
+changed.
+</p>
+<p>
+You can tell whether your files have been saved since they last changed by
+the save icon that appears next to the file name above each file. Also, the
+notebook label will show an asterisk (<code>*</code>) after any file that
+hasn't been saved.
+</p>
+<p>
+You can save the current file by selecting the
+<guiseq><gui style="menu">File</gui><gui style="menuitem">Save</gui></guiseq>
+menu item, or using the <keyseq><key>Ctrl</key><key>S</key></keyseq> keyboard
+shortcut.
+</p>
+<note>
+  <p>
+    Saving only saves the <em>currently focussed</em> file, which is the file
+    containing the cursor. If you can't tell which file is focussed, you can
+    click on the file to focus it before saving.
