Keys and commands
Every hotkey of the game client and every chat command a player can use.
The client is MuMain, an open-source remake of the classic client, with a few windows of our own. Press J in the game for the list of commands the server accepts from your character.
Windows#

| C | Character window. Its fourth button at the bottom shows the advanced stats: critical, excellent and double damage, ignore defense, reflect and more, and your Combat Power. |
| I or V | Inventory |
| K (inventory open) | Jewel bank, also opened by the jewel button in the inventory. See Vault and jewel bank. |

Client commands#
The client handles these itself. Most act on the player you selected or face.
| Command | What it does |
|---|---|
/trade | Trade with the player next to you (from level 6) |
/party or /pt | Invite the player to your party |
/guild | Ask to join the player's guild |
/union, /rival, /rivaloff | Guild alliance, hostility, end of hostility (guild masters) |
/duelstart, /duelend | Challenge to a duel (from level 30), end it; a fair duel is ranked, and ending it after the first point loses it |
/filter <words> | Show only chat lines with these words; without words, show everything again |
None of the client commands work in Chaos Castle, and /trade doesn't work in battle zones. There are no personal stores: sell and buy at the auction.
