You generally use a remote control, but some have on-screen support as
well, so you don't need to have the full IR keyboard at hand to use it.

I've seen it. That's one of the reasons I want the on-screen keyboard as a
client, so that it is easy to write support for any type of "keyboard"
you'd like.

For touch screens only, using focus will work, and is indeed better than
what I suggested, since it would work without any support in widget sets.
With a mouse, you'd have to require it to be the last window you clicked a
mouse button in (I haven't looked into what is considered window focus in
Nano-X, does it require a click?), to avoid problems if there are windows
between the one you want to write in and the on-screen keyboard, but that
should be trivial.
Good suggestion. I think this would be easier to do than what I suggested.
