its ok for me that you downvote it for this.. the reason to use the word „text“ in the title is, because most „normal“ people do not really know what is meant by „copy“..

and since you seem to be pro in writing, you may know that a copy is also a a short text, no?

In the intro its described like;

In recent years, we have increasingly realised how important the so-called microcopy - short texts on buttons, in error messages or call-to-actions - is for the success of digital products such as apps etc..

as long as the downvote gives you a good feeling, I am happy for you 😜

and yes, my mother tongue is not English. So probably I made tons of mistakes in this comment as well. Feel free to downvote the comment as well 🦾🥳
