TimeConstraint is an option for various algorithmic functions which specifies how long to spend trying a particular transformation or part of an algorithm.
Assumptions is an option for functions such as Simplify, Refine, and Integrate that specifies default assumptions to be made about symbolic quantities.
Context
(Built-in Mathematica Symbol) Context[] gives the current context. Context[symbol] gives the context in which a symbol appears.
$DynamicEvaluation is a symbol whose value is True if it is evaluated as part of the evaluation of a Dynamic.
$PerformanceGoal gives the default setting for the option PerformanceGoal for graphics and other algorithmic functions.
$SystemCharacterEncoding gives the default raw character encoding for the computer system on which Mathematica is being run.
