trigger "continue" button in tel field using tablets/mobile phones

Using pads/tablets or mobile phones only (please open both links with your tablet/mobile phone):

I can trigger in a text field if a user presses enter like here:

Does anyone know how I submit the form when the field is specified as "tel" (user friendly keyboard opens) and the users clicks "finished" or "continue" etc.

Thanks for any help!
