Can we fire events on key press in Lightning for Salesforce?

Hello Shariq,

Here is a lightning code sample.

<aura:application >
    <aura:Attribute name=’val’ type = ‘String’ />
    <ui:inputText value='{!v.val}’ keyup=”{!c.search}” />
</aura:application>
({
search : function(component, event, helper) 
{
    if(event.getParams().keyCode == 13){
        alert(‘Enter key pressed’); // Do your work here fire the event
    }
}
})
