   predefined glue widgets described in "<hlink|Containers, glue, refresh and

+  Text attributes may be changed for <scm|text> widgets and many others by
+  enclosing them inside what we'll name <with|font-shape|italic|style
+  widgets>. These attributes are <scm|mini>, <scm|monospaced>, <scm|grey>,
+  <scm|inert>, <scm|centered> and <scm|bold>, and respectively: reduce the
+  size of the widget, choose a <tt|monospaced font>, set the color to
+  <with|color|grey|grey>, deactivate the widget (meaning it is rendered, but
+  greyed out and inactive), center it and choose a bold face. Here is an
+  example:
+
+  <\session|scheme|default>
+    <\unfolded-io|Scheme] >
+      (tm-widget (example3)
+
+      \ \ (hlist\
