Reply To: GREP Positive Look Behind Issue

That is definitely a weird issue, I tried using ~M\K\r+ and InDesign would only find the instances where the column break was on its own line with nothing else but at the same time InDesign couldn’t find anything if the column break was at the end of a paragraph or if the column break had anything else in front of it while on its own line.

I was just playing with other break characters, have you tried the standard carriage return (~b)? I just tried (?<=~b)\r+ and it seems to find most instances in my test doc. It’s not a perfect work around, but it might be a faster alternative to doing it by hand even though you probably have to go though and review each instance it finds.
