According to https://github.com/mintty/mintty/wiki/Keycodes#altgr when the keyboard layout does not have a keycode for an AltGr combination, the AltGr key is treated as Alt instead.
I have the following entry in ~/.inputrc "\e'": "`" # Alt+' -> ` and, as AltGr+' is not a valid combination in my keyboard layout, until mintty 3.1.6 by pressing it I was obtaining the wanted backtick character. However, since mintty 3.1.7, this key combination now produces nothing. One has to explicitly use LeftALt+' to obtain the backtick. This is inconvenient because one needs to use both hands, while AltGr+' can be easily triggered with a single hand. -- Enrico -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
