Wing will highlight matching braces in green when the cursor is adjacent to a brace. Mismatched braces are highlighted in red.
You can cause Wing to select the entire contents of the innermost brace pair from the current cursor position with the Match Braces item in the Source menu.
Parenthesis, square brackets, and curly braces are matched in all files. Angle brackets (< and >) are matched also in HTML and XML files.
