I know a little bit of something about macros that increase efficiency when I use Microsoft Word. off the top of my head, and without opening MS Word, I know I have a macro that will "update all fields" in a document, that will "delete unused styles" in a document, and "convert all tables to text" in a document. Macros are powerful. They are not good or bad - they just exist. My purpose for using a macro is to automate one or many tasks that would take longer if I did performed the steps manually. I have been using macros for nearly as many years as I've worked as a technical writer.
That's why, when I read an article like this one - The scam that knows your name and home address – here’s what to do - I feel sad.
