Cell > Show Expression (Mathematica Menu Item)

Show Expression toggles between the expression and display forms of a cell.

AtomQ (Built-in Mathematica Symbol)

AtomQ[expr] yields True if expr is an expression which cannot be divided into subexpressions, and yields False otherwise.

BenfordDistribution (Built-in Mathematica Symbol)

BenfordDistribution[b] represents a Benford distribution with base parameter b.

ByteOrdering (Built-in Mathematica Symbol)

ByteOrdering is an option for BinaryRead, BinaryWrite, and related functions that specifies what ordering of bytes should be assumed for your computer system.

CellEvaluationFunction (Built-in Mathematica Symbol)

CellEvaluationFunction is an option to Cell which gives a function to be applied to every expression from the cell that is sent to the kernel for ordinary evaluation.

ContentSelectable (Built-in Mathematica Symbol)

ContentSelectable is an option to constructs such as Inset, Graphics, and GraphicsGroup that specifies whether and how content within them should be selectable.

ContraharmonicMean (Built-in Mathematica Symbol)

ContraharmonicMean[list] gives the contraharmonic mean of the values in list.ContraharmonicMean[list, p] gives the order p Lehmer contraharmonic mean.

DeclarePackage (Built-in Mathematica Symbol)

DeclarePackage["context`", {"name_1", "name_2", ...}] declares that Needs["context`"] should automatically be executed if a symbol with any of the specified names is ever ...

DiracComb (Built-in Mathematica Symbol)

DiracComb[x] represents the Dirac comb function giving a delta function at every integer point. DiracComb[x_1, x_2, ...] represents the multidimensional Dirac comb function.

DirectoryQ (Built-in Mathematica Symbol)

DirectoryQ["name"] gives True if the directory with the specified name exists, and gives False otherwise.
