"What's it doing now"? Simple - it's nose-high and climbing. Best get the nose down and back to our cleared FL, then. No need to worry about laws, modes, or pushing buttons - just do the intuitive thing and the aircraft's systems will comply in a fairly transparent manner.
- delightfully simple, but maybe some prefer to leave it to the software engineers to sort out.
