The thing about my problem that you dont understand is, im not saying that my radar is not working in su33. Try to imagine this, u open dcs world, you go in the options then controls, and you pick a random jet lets say its f15c and u want to change its "vertical scan mode" button to "tab", u click on modes, u click on that keyboard section of the vertical scan mode, u clear the earlier assigned button ("3" if im not mistaken) , you double click on the little empty cell that you just cleared, the button assigning window is opened now, it wants you to press a key and if u want press a modifier. Right at this point if i press my tab button (which is right below tilde and right above capslock) nothing happens game doesnt acknowlegde it, game doesnt see that im pressing a button, Button assigning window stays empty, game behaves like i didnt even press "tab". Do you understand it now?
