NotebookEvaluate (Built-in Mathematica Symbol)

NotebookEvaluate[notebook] evaluates all the evaluatable cells in notebook.

Defer (Built-in Mathematica Symbol)

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

Unevaluated (Built-in Mathematica Symbol)

Unevaluated[expr] represents the unevaluated form of expr when it appears as the argument to a function.

HoldComplete (Built-in Mathematica Symbol)

HoldComplete[expr] shields expr completely from the standard Mathematica evaluation process, preventing even upvalues associated with expr from being used.

ReleaseHold (Built-in Mathematica Symbol)

ReleaseHold[expr] removes Hold, HoldForm, HoldPattern, and HoldComplete in expr.

HoldForm (Built-in Mathematica Symbol)

HoldForm[expr] prints as the expression expr, with expr maintained in an unevaluated form.

HoldAllComplete (Built-in Mathematica Symbol)

HoldAllComplete is an attribute which specifies that all arguments to a function are not to be modified or looked at in any way in the process of evaluation.
