Automatic deletion of blank lines in Pages

[Cicolidis]

Hi, I'd like to know how can I automatically delete all blank lines of Pages document. I guess it has something to do with "search and replace" but I don't know the command. I hope someone can help me. Thanks in advance.

On my non Mac keyboard, a search replace using "alt enter alt enter" -> "alt enter" works.
The "alt enter" shows up as "\n" in the search and replace boxes.

Can't get it to work using an Apple keyboard. It used to be easy.
Wonder why the made it hard?
