I'm using Linux Mint 15 x64, and I want to add a new key mapping for curly braces. I'm using italian keyboard layout. On Windows I'm used to creating curly braces by pressing
(Left Ctrl && Left Shift && Left Alt) && (è || +)
By è and + I mean the two keys to the right of the P key, those that create square brackets when only Left Shift is down.
How can I enable curly braces creation as I'm used to on Windows?
