In NetHack, the en dash or short dash symbol (-) serves the following purposes:

• - represents a horizontal wall.
• - represents an open door in a vertical wall.
• - is used to draw horizontal rays.

• Pressing - followed by a direction will cause you to attack in that direction regardless of what is there - this is useful for attacking invisible or mimicked foes, pets or peaceful denizens of the dungeon, without a prompt for safety.
• For some item prompts, pressing - chooses your hands instead of an item, e.g. you can engrave with your finger, wield nothing and fight bare-handed, or apply grease to your hands. For other item prompts, you will mime performing the action instead.
• In a menu, pressing - deselects all items.
