Defer

Defer[expr]
yields an object that displays as the unevaluated form of expr, but which is evaluated if it is explicitly given as Mathematica input.

Defer[expr] returns an object which remains unchanged until it is explicitly supplied as Mathematica input, and evaluated using Shift+Enter, Evaluate in Place, etc.

Defer gives an object whose evaluation is merely deferred until it is explicitly given as Mathematica input; HoldForm gives an object that is never evaluated.
