This is quite unfortunate because I want to be able to use both the BT
keyboard (Thinkoutside Stowaway) and FBReader.
Actually the hardware keys are function keys, so try pressing F2-F8 etc
on your usb keyboard (I forget what is what, but you'll figure it out
quick)
This of course is far from optimal, since those keycodes are not fun if
you want to use a usb keyboard with VNC or some other remote desktop
tool on the 770, as then you are not able to use function keys for
anything else - but that's another story.
It's a possibility for you anyway.
