How may I identify the line return/carriage return in Writer?

Hello
I need to do something I used to do with Word 2007 and 2010 but I don’t know how to do the same in Writer.
Let’s imagine I have a document with these names.

  1. JOHN
  2. PAUL
  3. MIKE

Okay. Every name jump to the next line, so they have a line return or carriage return if you prefer.
Ok.
That, in Word is controlled with the character ^p
So if you tell Word find me the ^p character and (for example) replace it with an hyphen -
what Word would do is this

  1. JOHN-2. PAUL-3. MIKE
    Because it will search for the line return and replace it with an hyphen -
    But how may I do this in Writer?
    I have seen the search dialog box which is full of options and possible settings to search for, as color, font types, etc. but I did not find how to search the line return ?

You could search for: \n (line break) or $ (paragraph),
see also → Find & Replace doesn’t find paragraph marks.

The easiest way

Install the extension → Alternative dialog Find & Replace for Writer.

the easiest way no longer exists, this is about all I ever need find and replace for. Any other workarounds? Libreoffice 5.3.3.2

@meika: I updated the links in the question.

It works wonderful !!!
THANKS !!!
I’m using the extension is very very easy, I love it.
