Some problem you might interested in.

Could you separate the "Enter"? I should put it another way, can you stop in-game operations from the menu screen? I mean when I save the game, sometimes I'm behind a door, I use F2 then push enter to save the game. Question is when I push enter, the door will open at same time. And sometimes I didn't ready for it. Another situation is when I behind the switch to end this level, I might save the game because I haven't to get 100%. So when I push enter, I will pass the level and save the game. I can reload it, but there has another problem, when I reload, the file keep the switch is used, so I reload then I pass.
These two questions are very personal, so you could ignore these.
