It's not documented in the Keyboard Information that your character can move diagonally. This is very important for fleeing a fight, since the enemy cannot move diagonally. Also it minimizes movement, which consumes food. it's strange that the keypad does not work for movement, since it incorporates all directions. Instead, you have to use the Home/End and Page Up/Down keys which is not intuitive. Note: mouse-clicking doesn't allow you to move diagonally. The convenient Spacebar can also be used for selecting items and closing pop-up messages. Also, the Delete key can drop a selected item, which is much simpler than having to press Alt + 1-5 every time. Finally, the F11 key can be used to toggle Window/Fullscreen.
