Sometimes I want to use the large thumb onscreen keypad on my N810.
Most times the small (stylus) keypad pops up but I need a pen to key in something. The story is when I click with my finger on an input field (how does this non-multitouch device detect this ??) the large keypad should appear but in many cases the small pen keypad still appears.
Unchecking 'Enabling stylus input method' in the Control Panel -> Text input settings -> Onscreen keyboard results that no keypad at all pops up in most cases.

How can I enforce (or can I tweak some code ??) so that I can popup the large keypad on demand, or even ALWAYS ? The finger click method does not work in many cases.

You can toggle between the small and large keyboard with the center D-pad button. Do this when the keyboard is visible...

I tried this, but when I slide open the physical keyboard (to get access to the center d-pad key) the onscreen keyboard disappears. I tried all buttons on top and left of the device as well but that didn't work either.
Is there a apecial trick for it ?

Some would ask now "why don't you use the physical keyboard ?" Reason: no digit keys without shift and special characters are placed at a completely different location.

try pressing the input field harder with your thumb

This does not work in many cases (particularly low input fields which are less than 40 pixels high): the small keyboard still pops up.
