Pop up look up on any String Text Field Event

It will be hard to catch the [tab] click event. The problem is that the [tab] key is reserved for changing an active element in a browser.

The [Enter] key will be easy to catch. I would do the following:

define("ContactPageV2", [], function() {
	return {
		entitySchemaName: "Contact",
		attributes: {},
		modules: /**SCHEMA_MODULES*/{}/**SCHEMA_MODULES*/,
		details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
		businessRules: /**SCHEMA_BUSINESS_RULES*/{}/**SCHEMA_BUSINESS_RULES*/,
		methods: {
			onEntityInitialized: function() {
				this.callParent(arguments);
			},
			onPhoneClick: function(e) {
				if (e && e.keyCode === 13) {
					console.log("show popup");
				}
			}
		},
		dataModels: /**SCHEMA_DATA_MODELS*/{}/**SCHEMA_DATA_MODELS*/,
		diff: /**SCHEMA_DIFF*/[
			{
				"operation": "merge",
				"name": "AccountPhone",
				"values": {
					"layout": {
						"colSpan": 24,
						"rowSpan": 1,
						"column": 0,
						"row": 4
					},
					"keyup": {
						"bindTo": "onPhoneClick"
					}
				}
			}
		]/**SCHEMA_DIFF*/
	};
});
