A macro instruction is a computer-based command that allows users to automate certain tasks. Synonyms for macro instruction include macro command, macro code, macro script, and macro function. These terms are often used interchangeably and can refer to any type of pre-recorded sequence of instructions or keystrokes that automate repetitive tasks. Some popular macros include those that automate repetitive formatting tasks in Microsoft Excel, or macros that automatically create a table of contents in Microsoft Word documents. By using macros, users can save time and reduce the risk of errors associated with repetitive tasks. As technology and automation continue to advance, the use of macro instructions is likely to become even more widespread.
