It's not a matter of safer or not. using ctrl+enter simply inserts a literal newline character ('\n'). Not only is it just as safe, it also requires less parsing by the Warcraft III engine since it doesn't have to translate it to anything (whereas "|n" has to be converted to '\n'). Not only does it use one less character as stated above, but the tooltip in the editor also shows the line break when editing the tooltip, making it easier to edit. It also uses one less key press to type.What's a space break?
