Saving

Save is very simple. You have to just press S(s + shift) and the game is saved.

To Load the game, you just have to type the same name as in the saved file. Example: What is my name ? Jack, and I am(whatever). I start the game. Wow!It is late! I have to stop playing now! I press S. Yes, I do really want to save. Next day: What a wonderful day to play Nethack! I start the game. What is my name? I type Jack(Note: big letters matter). I press OK. Now I have loaded my saved Nethack file!
