This discussion recently came up on emacs.stackexchange..
http://emacs.stackexchange.com/a/21524/115
The emacs manual (C-h i g (emacs) Modifier Keys) says the below:
"A <Control>-modified alphabetical character is always considered
case-insensitive: Emacs always treats ‘C-A’ as ‘C-a’, ‘C-B’ as ‘C-b’,
and so forth. The reason for this is historical."
But I am able to bind something like
(global-set-key (kbd "C-S-n") #'previous-line)
and have C-n and "C-N" call different commands.
Does that piece of information about Control-modified alphabetical
characters need correction or clarification?
Thanks.

Did you try that on a text terminal as well?

Not sure we want to enter these details in a user manual. Also, "C-N"
and "C-S-n" are not the same thing in this context.

I think it would make sense to at least mention these wrinkles in the
user manual -- many people don't care about running Emacs in a terminal,
and being able to bind shifted alphabetical characters opens up a whole
new range of user-definable keystrokes.

It's OK to mention that, but please also add a note that this only
works on GUI frames.
