When they are happy with their profession, they may continue by hitting 'D' for 'done'. The player's stats affect what professions he or she may be. The 's' key is called the brace key, what this will do is brace a player so they may attack in any of the given directions without actually moving in that direction. Example - l will make the character run to the right. These movement keys can all be redefined to the player's liking by using the 'C' configure command.
Many people like to reconfigure the movement keys to the number pad, which is fine.
To attack a monster in hand to hand combat, all a player must do is move into that monster, if that monster is in an adjacent square. This command is used to to determine what an item is made of, if an item has special properties, the cost, etc. Thus, if a player is on top of a chest, they can open that chest by using this command. This is also how a player can enter buildings, open doors, and apply handles. One can repeat a command many times by preceding it with a number.
