This appeared in my Mac directions post above, but is (I think) worth re-asking:

Is it normal/expected behavior that the N810 hard keyboard doesn't work when the program is in the mouse mode?

If it is, that's a change I would suggest; that way those of us with hard keyboards can make the most of the screen/keyboard real estate. If not, then something isn't working. Now, when it's in keyboard mode, where there's a small mousing area and an on-screen keyboard, the hardware keyboard also works, but half of the screen is wasted with the (very nice) on-screen keyboard.
