I do not need to hightlight the numbers itself, i want to highlihg the lines.
having [10,12,20,34,41] I want to highligt tenth, twelfth, twentieth, thirtyfourth and fourtyfirst LINES, but not the numbers.
I know that the could be regexp like (10|12|20|34|41), but there is no the numbers in the text.
In this case, you cannot change the color of particular line numbers. Howerver you can toggle bookmarks on particualr lines if you would like. Bookmarks can be set by using SetBookmark Method (Selection Object) if you write a macro.
