Skip Mission mod

You press two keys at once (for example CTRL + 0) to skip a story mission.
If you die three times in a row, you can skip a mission, but that's really annoying.
If I've already played a mission because the game has crashed, or if the mission is too hard, I want to skip it, but it's always annoying to try to fail three times, because you have to get yourself killed, or something similar to fail the mission three times, so just pressing a key (or two in this case) to skip a mission would be very nice.
I want to hold a key and press another key so I don't accidentally skip a mission when I don't want to skip it.
