• + = (plus) the sequences in a pattern (1 or more sequences)
• ? = (question mark) sequences in a pattern (either 0 or 1 sequences).
You must enter an escape sequence (CTRL+v) prior to entering
the ? regular expression.

the beginning of a sequence or range, it matches on everything BUT
the characters specified.
• $ = (dollar sign) the end of the output string.
