This line is not working for some browsers, so please specify the widget with id and then use the widget to get the "real" button to trigger the Keys.Tab.
For example,
<button id="FocusOnMe" label="FocusOnMe" ...

sendKeys(engine.$f("FocusOnMe").$n("btn"), Keys.TAB); // the btn is the real button in the Button component
