24U Commenter is a COM plug-in for Metrowerks CodeWarrior. It allows you to comment out or uncomment the current selections much faster. It adds "Un/Comment Selection" as a new menu item to the Edit Menu. You can also assign a shortcut to this command, or add a button to the edit window's button bar. To comment out or uncomment a block of text, you can simply highlight the text and click on the 24U Commenter's button or use the assigned shortcut.
Mac OS 9.0 or later, CarbonLib, Codewarrior 6.0 or later
