Which measures of yield curve risk can measure shaping risk?

As stated, however, I have so many questions about this one, simple statement

1.What’s the difference between curve and shaping risk

  1. do we need to memorize all the measures for both of them and what are they

here is the official answer to the question, but I would love to know where they come from, thanks

Key rate durations and a measure based on sensitivities to level, slope, and curvature movements can address shaping risk, but effective duration cannot.

Yield curve risk means a parallel shift in the (par) yield curve.

Shaping risk encompasses steepening, flattening, humping, butterflying, and anything else other than a parallel shift of the (par) yield curve.
