Mathematica's scheduled tasks provide a way to set evaluation of arbitrary expressions in the future. Tasks can be scheduled for one-time evaluation, or for repeated ...

Evaluate in Place evaluates a selection in place.

StackComplete[expr] evaluates expr with intermediate expressions in evaluation chains included on the stack.

StackBegin[expr] evaluates expr, starting a fresh evaluation stack.

Interrupt Evaluation interrupts the current operation being performed by the kernel.

StackInhibit[expr] evaluates expr without modifying the evaluation stack.

Mathematica normally takes any expression it is given, and evaluates it as far as possible. But built into the Mathematica language is a collection of flexible primitives ...

"EvaluateCells" is a front end token that sends the selected cells to the kernel for evaluation.

"EvaluateInitialization" is a front end token that evaluates all the initialization cells in a notebook.
