Here is a way that removes the lines containing "YOURTEXT" completely:

Open the Replace dialog
Enter the following search string: .*YOURTEXT.*[\r]?[\n] (replace YOURTEXT with your text)
Enable "Regular expression"
Disable ". matches newline"

The given regular expression matches both Windows and Unix end of lines.

If your text contains characters that have a special meaning for regular expression, like the backslash, you will need to escape them.

Using regex and find amp replace  you can delete all the lines containing  region without leaving empty lines  Because for some reason Ray s method didn t work on my machine I searched for     region   n    n   region    and left the replace box empty   That regex ensures that the if  region is found on the first line  the ending newline is deleted  and if it is found on the last line the preceding newline is deleted   Still  Ray s solution is the better one if it works for you
