+/**
+ * <p>
+ * Command to sort the key interactions in a sequence of events. An example, the sequence
+ * to write the upper case D
+ * <ul>
+ *   <li>press shift key</li>
+ *   <li>press D key</li>
+ *   <li>release shift key</li>
+ *   <li>release D key</li>
+ * </ul>
+ * 
+ * is transformed to the sequence
+ * 
+ * <ul>
+ *   <li>press shift key</li>
+ *   <li>press D key</li>
+ *   <li>release D key</li>
+ *   <li>release shift key</li>
+ * </ul>
+ * 
+ * in which the first pressed key (shift in this case) is always released last. The same is done
+ * for the alt and the ctrl keys.
