Key phrases are reversed words and so are separately compiled via the compiler. They Express a predefined meaning to the compiler and as a result can't be produced or modified.
Be aware - this system was at first titled "C# Fundamentals - Part 1", but is renamed to far more properly reflect the target audience and material of the class.
