Now this seems to be a very serious problem. I'm trying to control all keys in D3. That means I have to catch all the keys that were pressed in my program (and that is eg. ScrollLock, ESC, Tab etc.) but not to let, if don't want to, to know the program that the key was pressed. For instance if I press TAB I want do some action and I don't want the program to skip to another TabEnbled component? Please, help me. What should I do? Is it possible? I hope so.
