Actually, I just checked, and you can in Cocoa. Just uncheck all the
modifiers in IB, and the menu will just show the letter (capitalized). Check
the Shift modifier, and the menu will show that along with the letter.
Furthermore, the keys automatically trigger the menu item (at least when a
text view doesn’t have focus). (I mapped A without any modifiers to an About
panel, and it worked fine.)

The problem isn’t displaying un-modified keys, the problem is having those menu
items work reliably. Un-modified menu items are very far back in the responder
chain; if there is a responder before them, the system will never even attempt
to deliver the key event to those items. While your test application happened to
have no first responder, that is in practice a rare occurance.
Basically, the command key is magic. It goes through a completely separate code
path. Command-modified key events are intercepted very high in the event
processing hierarchy, then routed to the separate method -performKeyEquivalent:
in a completely different order than regular keydowns. Command-keyups are simply
swallowed by the system and never seen again. Because of the special command-key
logic, menu items get first crack handling the event where they would ordinarily
never see it.
In summary, yes I could put the un-modified key shortcuts in the menu, but it
would be misleading because they would sometimes do nothing when it looked like
they should. And the character-parsing logic still has to be implemented in my
view anyway, because it’s key and prevents the menu items from being executed by
their key equivalents.
