C-/ is a key sequence, but it is not a character sequence. The character sequence Emacs expects is the single character with octal value 037. Almost all terminals send this character when the key sequence C-_ is typed. Many terminals also send this sequence when typing C-- (unshifted _) or C-7 or sometimes even C-/. The Windows Console "terminal" supports none of these extra key sequences. If you really miss typing C-/, I recommend using PuTTYcyg instead of the console window. -Mark -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
