Controling \R By default, the \R metacharacter matches any Unicode newline sequence. To set display: none, it hides the complete element with content, while visibility: hidden means that the contents of the element will be invisible but the element covers its size and position. In that case, Out-String will still output the string as a single, multiline string. The newline character(s) at the end of the string will be stripped by the command substitution. WriteLine("Attempting to match each line of an input string with '$':"); match = Regex. But having to break the string in several places and adding the values like this is unreadable when you have more than just simple addition.
