Returns a context containing elements from this context, but without an element with the specified key. Keys are compared by reference, that is to remove an element from the context the reference to its actual key object must be presented to this function.

fun minusKey(key: Key<*>): CoroutineContext
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

plus

Returns a context containing elements from this context and elements from other context. The elements from this context with the same key as in the other one are dropped.
