Then I don't think you will have any problems. I seriously cannot remember any key combinations you need to use in those games. Except perhaps hotkeys. And firstly you needn't use hotkeys and secondly if you do you are paused anyway so can take as long as you want to do it. But I personally never really have used the hotkeys---they simply aren't necessary at all.I can use shift and space bar when using the mouse. It's multiple keyboard keys at the same time that I struggle with eg. running and jumping at the same time while maintaining direction.
The only thing which might be a problem is the console. You open it by pressing § which on a Danish keyboard requires you to press shift + ½; but you can live perfectly fine without the console. The console is only for if you are modding or cheating.
