I shall address all the kind replies above with gratitude.
I am using this iPad in landscape. The issue is even worse in portrait making the target thinner.
The emoji button thought is also a good one, but for me the very large globe is mainly for the Japanese keyboard, which is needed. It is a good thought though.
Sadly, I am not quite in a position to spend extra money, no matter how small, for basic function, although I do understand spending money to ‘buy a steering wheel for a car’ would normally be easier for me. I appreciate the aftermarket third party thought, but sadly, not achievable. (Nor should Apple really expected that as the only fix, but that doesn’t reduce my gratitude to you for the thought and real suggestion :) )
The two number lock buttons [.?123] either side of the tiny space are fully redundant, I’d even be happy to turn those off completely as everything they provide can be obtained without any modifier, or just by pressing shift.
So unfortunately the issue is still unsolved, but I wanted to warmly thank people’s suggestions so far. I still kindly hope someone else has more suggestions? I hope the question can be left open please.
Thank you ^.^
