> How do you get keyboard commands into the inner rio?

Same as you do mouse commands: you pass them in based
on some sort of focus.

The only difference is the focus mechanism, which must
be something other than the cursor position for the
keyboard commands.

For example, I use sigrid's riow manager with plenty
of subrios and it works fine.  The focus mechanism used
is based on window labels: if the window has a label
starting with "rio:" then the outer rio doesn't "spill"
the prefixed key events into its own riow instance but passes
them as usual to the inner rio, which can do the same again.
The label mechanism *is* hacky and it's just something that
I implemented on the spot to do what I wanted. There's no
inherent reason that something more graceful couldn't be
done.
