The row of entry buttons under the phone's formula bar, on the same surface as the studio
toolbar: the three inputs (letters, numbers, date) at the left, Tab and Enter in the middle, and
cancel / commit at the right.
Remarks
Presentation only. The host owns the textarea and the session, so every action is a callback it
runs inside the gesture, which is what lets the browser raise or switch the keyboard. Each input
button opens its input: tapping one is never a no-op, whether or not a keyboard is already up.
