     <strong>Passing JVM Arguments to Jalview</strong><br /> If you need

+    <strong>Changing Jalview's 'Look and Feel'</strong> <br />If you
+    are experiencing issues with the font size or layout of Jalview's
+    GUI, you can try changing Jalview's 'Look and feel' by
+    specifying a custom system property 'laf' on startup (see <a
+      href="../memory.html#jvm">setting the JVM's memory</a> for
+    instructions on how to do this for your platform). <br />For the
+    Jalview standalone executable jar, simply provide one of the
+    property settings before the -jar argument

+    <li>-Dlaf=crossplatform (Java's Metal Look and Feel)</li>
+    <li>-Dlaf=nimbus (Java's alternative Nimbus Look and Feel)</li>
+    <li>-Dlaf=mac (only has an effect on OSX)</li>
+    <li>-Dlaf=gtk (only has an effect on Linux)</li>

+    <li>-Dlaf=quaqua (macOS only. Force attempt at old macOS theme)</li>
+    <li>-Dlaf=vaqua (macOS only. Force attempt at modern macOS theme)</li>
+  </ul>
+  The currently configured look and feel is logged to Jalview's console.
+  Once the look and feel has been changed, it will be stored in
+  Jalview's .jalview_properties file for future Jalview sessions.  This property is <strong>PREFERRED_LAF</strong> and can also be used to set the Look and feel by editing your .jalview_properties file.
