How to change soft returns with hard returns using the Microsoft-Word find-and-replace function.
How do I do this?
Open the find-and-replace window (CTRL-H) and Find ^l (lower case L) and Replace with ^p (lower case P).

When using Libre Office Writer :

Open the find-and-replace window (CTRL-H) and Find \n (lower case N) and Replace with \n (lower case n). Under More Options check Regular Expressions

I know, both parameters are the same ! Don’t ask me why, but it works ….

Easy as that ! Greetz, M.
