Make a handler for LzKeys.onkeyup. Inside that handler, check
whatever conditions interest you (LzFocus.getFocus() == myView, for
instance) and then call the button action.
<canvas ...>
<handler name="onkeyup" reference="LzKeys" args="k">
Debug.write("key " + k + " up");
myButton.doSomething();
</handler>
<button id="myButton">
<method name="doSomething">
...
Does that work?
