The - symbol is used to represent:

horizontal walls: -
an open door in a vertical wall: -
part of a ray
Pressing - followed by a direction will cause you to attack that direction regardless of what is there, 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. This can be used to engrave with your finger, to wield nothing (and fight bare-handed), or to make your hands greasy. Selecting "-" when asked, "What do you want to eat?" gives the message, "You mime eating something."
Pressing - at a menu deselects all items. Supported by tty and curses interfaces, see menu controls.
