dojo.onEnterPress = function(ref, context, method){
    // summary: Shorthand utility function for hooking up enter-key handling to a text input. 

    var ENTER = dojo.keys.ENTER, callback = method ? dojo.hitch(context, method) : context, ev = "keypress";
    if(typeof ref == "string"){
        ref = dojo.byId(ref);

    }
    
    return dojo.connect(ref, ev, function(e){
        e && e.charOrCode && e.charOrCode == ENTER && callback();
    });
};

// example, call this._runSearch() when they hit enter in a textbox or on the search button:
dojo.onEnterPress(widget, this, "_runSearch");
dojo.connect(button, "onClick", this, "_runSearch");
