(global-set-key (kbd "H-g") 'keyboard-quit).
When the minibuffer is open and waiting for input, and I want to quit out of it, when I hit
H-g, the bell rings and I see the Quit message, but the minibuffer remains open and accepting input.
C-g works as expected: closes the minibuffer.
How can I make
H-g quit the minibuffer?
