I just debugged the current cotvnc because I can't send \ and | to the server. Maybe I simply don't understand how this keyboardthing works in cotvnc. When I look at "sendKey" I see that, for Shift-Alt-7 not \ arrives in c but / (i.e. code 47).

This patch is much less invasive than the other one available, and works in all applications such as firefox on Linux. I have only tested it againts a linux VNC server so it might break other servers.
