As you can manage anything from a USB bluetooth keyboard
located on the screen android tablet?
The fact that the keyboard is lost from the screen when the
mouse pointer appears! Any other navigation with mouse works fine.

Of course connected with mouse USB OTG adapter!
I only want to write the text with the mouse on the keyboard,
which is on the tablet screen.

Anyway what the Android keyboard;

Only with a mouse navigation and text to write - it is possible at all?
