Thanks Mofi! That worked
The only problem now would be juggling w/ another MACRO (select line, transform thru another MACRO, copy, etc, repeat process)
I wished UE had a built-in keyboard/mouse command for this function, though (at the same time, addressing the second issue I raised). Or a toggle to allow inclusion/exclusion of hard break/newline. Some of my regular tasks involve copying content from one source and inserting it to another and one of these tasks is very straightforward (no need to understand the context of the content), thus allowing a macro to reformat and isolate lines of text. What I have recently discovered (right after I post this topic) is replace the hard break/newline w/ line feed [0x0D 0x0A -> 0x0C], allowing selection of whole line (either by clicking at the line number at left or triple-clicking at the line of text) w/o the hard break/newline.
