     \brief The KeyNavigation attached property supports key navigation by arrow keys.

-    when an arrow key is pressed.  The following example provides

-        Rectangle {
-            id: item1
-            focus: true
-            width: 50; height: 50
-            color: focus ? "red" : "lightgray"

+    Key-based user interfaces commonly allow the use of arrow keys to navigate between
+    focusable items.  The KeyNavigation attached property enables this behavior by providing a
+    convenient way to specify the item that should gain focus when an arrow or tab key is pressed.
+
+    The following example provides key navigation for a 2x2 grid of items:
 
-    By default KeyNavigation receives key events after the item it is attached to.
-    If the item accepts an arrow key event, the KeyNavigation
-    attached property will not receive an event for that key.  Setting the
-    \l priority property to KeyNavigation.BeforeItem allows handling
-    of the key events before normal item processing.
+    \snippet doc/src/snippets/declarative/keynavigation.qml 0
 
-    If an item has been set for a direction and the KeyNavigation
-    attached property receives the corresponding
-    key press and release events, the events will be accepted by
-    KeyNavigation and will not propagate any further.
+    The top-left item initially receives focus by setting \l {Item::}{focus} to
+    \c true. When an arrow key is pressed, the focus will move to the
+    appropriate item, as defined by the value that has been set for
+    the KeyNavigation \l left, \l right, \l up or \l down properties.
+
+    Note that if a KeyNavigation attached property receives the key press and release
+    events for a requested arrow or tab key, the event is accepted and does not
+    propagate any further.
+
+    By default, KeyNavigation receives key events after the item to which it is attached.
+    If the item accepts the key event, the KeyNavigation attached property will not
+    receive an event for that key.  Setting the \l priority property to
+    \c KeyNavigation.BeforeItem allows the event to be used for key navigation
+    before the item, rather than after.
