return %^The second responsibility of a component is to handle user interface behavior. This usually means having a method for each link or submit button it displays. The Counter class has two such methods: <tt>#increment</tt>, which maps to the ++ link, and <tt>#decrement</tt>, which maps to the -- link. Their implementations are very simple:
<pre>
<b>increment</b>
count := count + 1
<b>decrement</b>
count := count - 1
</pre>
#{counter}
Methods that are directly mapped to links or buttons are sometimes known as <i>action</i> methods
<p>
You can use this editor to modify the <tt>#increment</tt> action method. For example, you can try changing it to
<pre>
<b>increment</b>
count := count + 2
</pre>
Test your changes with the counter above
#{incrementEditor}
