In NetHack, the hash mark (#) serves the following purposes:

• Press # to enter a specific extended command. Note that "#" cannot be the first character of the name of any NetHackWiki article, requiring it to be omitted from the title of extended command articles.
• On the skill screen, # denotes a skill that cannot be #enhanced any further.
• # can represent one of many dungeon features:
  • # # corridor
  • # tree
  • # cloud
  • # poison cloud
  • # sink
  • # iron bars
• In the inventory, # is used as an overflow character for items that are picked up when every other inventory letter is in use - in practice, this typically occurs with a picked-up loadstone, which ignores the inventory letter limit that would prevent you picking up most additional items. Boulders picked up while in the form of a giant or titan are also given hash mark slots in the inventory if all other letters are in use.

The following information pertains to an upcoming version (3.7.0). If this version is now released, please verify that the information below is still accurate, then update the page to incorporate it.

The glyph used for a sink is now {.
