+<h2>Explanation</h2>
+<h3>Operation</h3>
+<blockquote>
+When <em>evaluate</em> is pressed, the given expression is evaluated and the result is displayed in the result(s) field.
+In case of <em>list properties</em> being pressed, the result of the expression is taken as an object
+and the objects properties are displayed with their type and value in the the result(s) field.
+</blockquote>
+<h3>Expression</h3>
+<blockquote>
+Expression must be a valid javascript expression, e.g.<br><code>window</code>
+<br>or<br><code>document.body.innerHTML</code><br>or<br>
+<code>"Today: " + (new Date()).toString()</code><br>
+or<br>
+<code>"Cablecar".match(/ab.*c/)</code>
+<br>It is also possible to assign a value,
+e.g.<br><code>document.getElementsByTagName('H1').item(0).innerText="Hello World"</code><br>
+You may execute these examples by pasting them into the expression field.
+</blockquote>
+<h3>Result Type</h3>
+<blockquote>
+The type of the result of the given expression.
+</blockquote>
+<h3>Result(s)</h3>
+<blockquote>
+The result of the expression is implicitly converted to a primitive type by the javascript interpreter,
+if <em>evaluate</em> was pressed. When <em>list properties</em> was pressed, a <code>for (var i in obj)</code> loop
+is executed to list the properties. These object properties are in turn evaluated and their types and values
+are displayed.
