"But with carefully chosen keyboard macros to activate it, Mass Copy is quick, convenient, and powerful. Most users who have mastered it depend heavily on it. That certainly includes me"

This quote by Robert Patterson speaks to the power of Mass Copy, a keyboard macro that can be used to rapidly and conveniently copy big quantities of data. Patterson recommends that those who have mastered the use of Mass Copy have actually pertained to rely heavily on it, and he himself is no exception. This suggests that Mass Copy is an effective tool that can be used to save effort and time when copying large quantities of data. It is likely that Patterson is suggesting that those who have actually not yet mastered using Mass Copy should take the time to do so, as it can be a great possession in their work. By using Mass Copy, users can save time and effort when copying big amounts of information, and can be sure that the data is properly copied.
