Oh, that's bad. And no menu in application manager either?
just tried, it is arrow down on N810
Will check. But NDS has two displays so it is perhaps fullscreen on the bottom? Quite NDS specific. For Maemo either semi-transparent switchable or small on some side would be nice. For previous tablets there was also xkbd and xvkbd available with customizable layouts (usable also for dosbox and other stuff that needs keyboard).
