How to make a key binding to the left shift?

Question

I have a Mac keyboard and trying to assign the backslash character to the "left shift + `" combination.

However the following code:

(global-set-key (kbd "S-`")                                                        
                'insert_backslash)                                                 

(defun insert_backslash ()                                                         
  (interactive)                                                                    
  (insert "\\"))   

creates the binding only for the right shift key. How do I assign it to the left shift instead?

Answer 1

What does C-h k tell you when you use that key (press and hold Left Shift and hit `)? It should tell you exactly what Emacs calls that key. Then use what it tells you as the arg to kbd.
