Yeah. I tried to do this without the window manager and had trouble too.
That's why I chose twm2 since it has low overhead. The key bindings are
fine until you go into TV mode. I think it's because the TV view is a
separate window that gets put in front of the interface window. Since
there is no window manager to automatically focus the new window, all the
key bindings stop working.
