Replace paragraph break with line break

Please peruse this post:

Re: Replace paragraph break with line break (soft return)

This thread also doesn’t yield the intended result: I am trying to replace the paragraph characters with line break, can’t figure it out. Doesn’t have option for paragraph break, or does it, or i can’t figure that out either

The claim above is wrong. Correctly doing as described in the linked thread works as expected.
Of course, versions like are no longer of much interest - and rarely found in the wild.
(I tested with 7.0.4.)

My LibreOffice Version: Version (Build ID: 400m0(Build:3))

I would like to replace all paragraph breaks (enter) with line breaks (shift/enter).

LibreOffice displays a character somewhat similar to the Unicode character ↲ for line breaks (shift/enter)

Is there an expression for line break in the Replace box?

It is easy to replace line breaks with paragraph breaks (e.g., gedit) )with Search = \n (finds line break) and Replace = \n (replaces with paragraph break).

But the solution link above doesn’t work for LibreOffice.

Any suggestion?

Alt Macro is very complicated to use! (Abusive link removed.)

On UNIX-like systems (eg. GNU/Linux), typing the U+000A character (Ctrl+Shift+U, then “000a” in my case) works for me.
