There are buttons you can add to your tool bars to comment highlighted blocks of code. You can also modify your keyboard interface to add keystrokes to do the same thing. Tool bar edits are just a matter of using the standard steps for customizing toolbars. Look for the commenting options under the "Edit" functions.
For the keystrokes, go to Tools | Customize Keyboard and map your desired keystroke to the same Edit function.
