[osk] Allow multi-touch for capital button

[Sam Bull]

The keyboard should use multi-touch to allow uppercase letters to be quickly typed. That is, holding the caps button down with one finger should allow typing uppercase letters with the other fingers.

This can work with the existing design, if another button is pressed while holding down the caps key it should cancel the caps-lock when the user lets go of the caps button. If no other button is pressed before the user lets go, it should work as currently designed and enable the caps lock.

Adding this feature allows more intuitive input, allowing users to use this in the same manner as a shift button on a physical keyboard.

-- UX solution --

OnPress the SHIFT key, user should be able to type as many letters as they want UPPERCASE
OnRelease, it will revert revert to lowercase

In addition, it would be great if the [?123] key similarily allowed the user to input numbers and symbols, instead of alphabets. Holding down the [?123] should change the keyboard to the number view temporarily, until it is released. This would make inputting passwords, email addresses, and url's significantly easier.

Assign to Thomas but await design feedback

We have already got designs to support dynamic layout for inputting urls, email addresses and telephone numbers.

The suggestion above requires more design thinking for after 13.10. We need to perform some usability testing to understand how users type and their behaviours. This might be relevant for typing on tablets rather than phone.

I find myself naturally attempting to hold the shift button when typing only a couple of uppercase letters, and that is on the phone. Perhaps that's just me, but we'll see. Also, it might be confusing if it behaves differently on phone and tablet.

I agree with the proposed solution.
