The intended behaviour for Parchment on mobile browsers is that tapping anywhere will focus the input box and bring up the software keyboard. After accepting a command the keyboard will disappear, because on small screens it takes up too much space. On big screens it shouldn't be a problem having it disappear as it is easy to bring it up again by tapping anywhere.
If this doesn't match how it works on your device, please explain what does happen instead.
