A type of instruction that can produce several lines of machine language code is a Macro.
A macro (short for "macroinstruction", from Greek μακρός 'long') in computer science is a rule or pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to a replacement output sequence (also often a sequence of characters) according to a defined procedure.
Macros can be used to make tasks less repetitive by representing a complicated sequence of keystrokes, mouse movements, commands, or other types of input. In computer programming, macros are a tool which allow a developer to re-use code.
A hotkey is a button that triggers a single action such as opening a folder, executing an application, or stopping a song that's playing. A macro (like the ones in Microsoft Excel) is a chain of programmed actions that occur each time you hit a specific button (or launch the macro via an associated program).
