Subject: [PATH,curses] Fix control-{@[\]^_} and ESC
Date: Sun, 29 Aug 2010 13:23:09 -0000
From: Samuel Thibault <samuel.thibault@gnu.org>

Message-Id: <20100829232309.GD5158@const.famille.thibault.fr>
To: qemu-devel@nongnu.org

control-{@[\]^_} shouldn't get the 'a' - 'A' offset for correct
translation. ESC is better simulated as escape key.
