I will grant that "vi shortcuts" is strange, but "vi key bindings"? The operators/motions (or verb/noun) perspective is vital, but those operators and motions are not intrinsic properties of the keys they happen to be mapped to - indeed, you can remap them. The initial mapping is a totally valid question, particularly for lesser-used commands, and one that can quite reasonably be referred to by the phrase "vi key bindings".
