how to replace those 3 lines

There’s also the question about whether you want to JUST delete the lines containing those words/strings or “replace” as you stated later on. Replacement signifies that you want some “other” string in place of the selected lines. That would complicate the solution somewhat.

PS as well as looking at the solution @Alan-Kilborn suggested also look at Regex documentation here. Both your posts were very vague on substance with regards regex and the ctrl-shift-F. It would be in your best interest to start learning how to create regexes.

You’ll find some guidelines for doing such things HERE.
