Sorry for being off-topic, but I just checked how it is done on Jolla:

When you are using the touchscreen keyboard, all selected text gets automatically copied in the clipboard. However, when you connect an external keyboard (via Bluetooth), the Copy&Paste behaviour suddenly changes - you can of course select text with Shift+arrow keys, but the text does not get copied until you press Ctrl+C. And Ctrl-V then works for pasting as you would expect from a computer. Such behavior might be the same on BB10 devices when you connect an external keyboard, but why I'm saying this is that it sounds very promising that using TOHKBD should be very close to the real keyboard typing experience (still one day left to order ).
