KeyNav allows you to bind
navigation keys to function calls that will get called when the keys are pressed, providing an easy
way to implement custom navigation schemes for any UI component.</p>
<p>The following are all of the possible keys that can be implemented: enter, left, right, up, down, tab, esc,
pageUp, pageDown, del, home, end. Usage:</p>
<pre><code><b>var</b> nav = <b>new</b> Ext.KeyNav(<em>"my-element"</em>, {
<em>"left"</em> : <b>function</b>(e){
this.moveLeft(e.ctrlKey);
},
<em>"right"</em> : <b>function</b>(e){
this.moveRight(e.ctrlKey);
},
<em>"enter"</em> : <b>function</b>(e){
this.save();
},
scope : this
});</code></pre></div><div class="hr"></div><a id="Ext.KeyNav-configs"></a><h2>Config Options</h2><table cellspacing="0" class="member-table"><tbody><tr><th colspan="2" class="sig-header">Config Options</th><th class="msource-header">Defined By</th></tr><tr class="config-row expandable "><td class="micon"><a href="#expand" class="exi"> </a></td><td class="sig"><a id="Ext.KeyNav-defaultEventAction"></a><b><a href="source/KeyNav.html#cfg-Ext.KeyNav-defaultEventAction">defaultEventAction</a></b> : String<div class="mdesc"><div class="short">The method to call on the Ext.EventObject after this KeyNav intercepts a key.
