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. This combination works great when attacking monsters, too. 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. Use from telnet connection. Used to bind commands to keys. While braced you will not move. Clears the text screen.
