characters to match:
● . = (period) any single character (including a white space).
● * = (asterisk) the sequences in a pattern (0 or more sequences).
● + = (plus) the sequences in a pattern (1 or more sequences).
● ? = (question mark) sequences in a pattern (either 0 or 1 sequences).
NOTE: You must enter an escape sequence (CTRL+v) prior to entering
the ? regular expression.
● [ ] = (brackets) a range of single-character patterns.
