 Many thanks for the comprehensive and detailed information.
That box in Multiline mode is not a “list”, if you thought it was.
Yes, I mistakenly assumed that.

I think I understand the subject a little better now, but between theory and practice there’s still a gap with me.
Example:
 1
 2
 3
 4
 5
only matches as a whole:
 2
 3
 4
1. RegEx –> OK
 2. Multiple-lines –> ?

What am I doing wrong with “Multiline” or what else is a mistake of mine?
