Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. (Thus, they are called “macros” because a “big” block of code can be expanded from a “small” sequence of characters.)

A macro is an action or series of actions that can be repeated indefinitely. You are capturing your mouse clicks and keystrokes when you construct a macro. You can alter a macro after you’ve created it to make minor adjustments to how it operates.
