I'm not sure if it's possible to do what I'm going to ask you guys.
I'm working with a long document (more than 300 pages) that is already designed. I need to find along the 300 pages the letter x (lowercase) that has been use instead of the math symbol (we are using an Open Type font with all the math symbols) for describing measurments of magazines (its a brochure of poetic magazines in Spain)and replace it.
At the same time I need to change the name of each magazine that has been written in uppercase and I want it in lowercase and in different color. I try to find the way to do this with GREP code but it always finds and changes all the words in my document with the initial capital as well, not just the words that have all the letters in capitals.
