I had totally forgotten about touch.
I'll leave all of these things to you.

How does the OHR work with a touch-screen laptop? Do we need to extend the
backends to report whether the device has a touch screen? But you could use
both the mouse or a touch screen...

I'm going to add right-click controls to select a menu item without
entering, or cancel out of a menu, since it's often necessary to do both of
those in Custom; in particular Previous Menu isn't always available.
I don't know how to handle that with touch controls at all, but this is
probably only going to affect menus in Custom anyway, so it's probably not
necessary to support touch there.
