Hi,
I'm a new arduino user from Poland and I have discovered an issue connected with using my language in Arduino IDE. As I try to comment the line of code and using polish character "ś" , which keyboard combination is "AltGr+s" , the app starts to verify the code despite the fact that hotkey that does that is "Ctrl+r". The problem appeared for the first time in version 1.6.5. AltGr (right Alt) also triggers keyboard menu navigation but it shouldn't because only left Alt should do this.
