Carbon SetMenuItemCommandKey() can assign both a user-visible command 
key (what the user thinks they are typing) and a "virtual" key (what 
is actually typed).

A slight problem is getting a Carbon MenuRef from a Cocoa NSMenu. 
Undocumented Goodness <http://www.cocoadev.com/index.pl?NSMenu> 
mentions _NSGetCarbonMenu(NSMenu* aMenu), but I've never managed to 
make that work....

Anyway, assuming a MenuRef to, say, the Help menu, Carbon set the 
display keycode to Cmd-? and the virtual keycode to Cmd-/ , so it 
doesn't matter if Shift is down or not.

MenuRef helpMenuRef; // getting this is left as an exercise for the 
reader :) ...

// make Cmd-? work without having to hold down shift key
SetMenuItemCommandKey( helpMenuRef, 1, false, '?');
SetMenuItemCommandKey( helpMenuRef, 1, true, 0x2C ); // set virtual 
key to '/', i.e Cmd-slash
