Since this comes up from time to time, I just wrote up a script 
(pasted in below my signature) that you can drop into your 
'scripts' directory (preferably the one within your Settings 
Directory, given 5th item in the About box). Then Reload All 
Scripts from the Edit menu and you should be able to bind the 
command 'comment-block-toggle' to some key in preferences.
