The backslash in a regular expression precedes a literal character. You also escape certain letters that represent common character classes, such as \w for a word character or \s for a space. The following example matches word characters (alphanumeric and underscores) and spaces.
Regex(
	"Are you there, Alice?, asked Jerry.", // source
	"(here|there).+(\w+).+(said|asked)(\s)(\w+)\." ); // regular expression
"there, Alice?, asked Jerry."
(here|there).+
(\w+)
.+
(said|asked)(\s)
(\w+)\.
