not sure what's the problem. I've switched to kbd notation for all my
keybinding needs, because that way, you have a sure way to know what
the notation would be like, by calling the command describe-key. In
your case, perhaps try that.

I did notice some inconsistencies even with this, especially when
defining a non alphanumeric key. Here's a little write up:

-----------
Note: A keypress-combination such as “Meta+Shift+2” can also be
considered as “Meta+@”. So, in emacs, you might be thinking that both
of these code: “(kbd "M-S-2")” and “(kbd "M-@")” will work. Actually,
only the latter will work.

When writing a keybinding definition, for a key combination that
involves “Meta+Shift+‹key›”, you must use a version without the shift
key if possible. For keybinding involving “Ctrl+Shift+‹letter›”, you
must use the "-S". Examples:

 GOOD            BAD             Keystroke
 (kbd "M-A")   (kbd "M-S-a")   Meta+Shift+a
 (kbd "M-@")   (kbd "M-S-2")   Meta+Shift+2
 (kbd "M-:")   (kbd "M-S-;")   Meta+Shift+;
 (kbd "C-S-a")   (kbd "C-A")   Ctrl+Shift+a

A easy way to find out the proper syntax, is to call “Alt+x describe-
key”, then type the keystroke.

Note also, that keys involving “Ctrl+Shift+‹key›” cannot be
distinguished from “Ctrl+‹key›” when emacs runs in a text terminal
(i.e. telnet/ssh). So, this means best to avoid any binding with both
Control and Shift.

i reported the above as a bug sometimes late last year or this year,
but i think it got dismissed.

emacs's has a keybinding notation hell. For detail, see the section
“Representation of Keystrokes” near the bottom.
