%	Matches any string of zero or more characters.

[token]	Brackets enclose ranges or set, such as [1-9] or [klmnopq]. There are two ways of formatting a token: 1. Range Start-stop: Start is the beginning of the character range. "-" is a special character indicating a range. Stop is the end of the character range. 2. Set Comprises discrete character values in any order. Examples - [a4Bc],[abcdefg]
[^token]	The caret "^" before a token indicates non-inclusion. Examples - [^c-g] means any character that is not a `c', `d', `e', `f', or `g'.
