or

Regex=[[ \$\{(\w+)\} ]], Group=1

Highlight variable names like ${name}. Only the enclosed name is highlighted as keyword. The grouping feature is used to achieve this effect. If no capturing group index is defined (like in the first example above), the right-most group's match (highest capturing index) is returned.

Regex=[[ (\w+)\s*\( ]]

Highlight method names. Note that grouping is used again.

Regex=[[STO\xe2\x88\x91]]

Recognize Unicode characters in a keyword.
