Hi,
the question would be first, does the action fires that event when you press the enter key on the virtual keyboard?
if not, you'll need to find what is the exact keycode to catch, which is likely why it fails, you may have to listen to several different keycode to actually have a cross platform solution.
so your first step is to make this action work, then you can take care on the content and display itself.
Bye,
Jean
