As every programmer, I ] need my ][ square ] brackets.
But at the moment, I have to switch to US layout in order to type them on StackOverflow. Since Croatia is not a big country, it's not all that important... except Hungarian layout also has square brackets in same place: -[- AltGr+F and -]- AltGr+G.
Apparently the underlying software thinks I'm holding Ctrl when I'm in fact holding AltGr... which is not the same :-)
PS StackOverflow is not the only one, this is a rare, but sufficiently common problem: Code::Blocks is mapping AltGr+F as one of its shortcuts
