• %menu% <menuName>

• %chat% <command>
  • What it does: Executes a chat command for the player who clicks the item.

• %write% <command>
  • What it does: Allows the player to type another player’s name, then executes a command using that name.
  • Details: After clicking an item with this command, the player can type a name in chat. Once they do, the specified command will run, appending the typed player’s name to the end. This is particularly useful for commands that require targeting other players (e.g., teleporting or granting permissions).

  • Details: When an item with this command is clicked, a message is printed in the chat for the player. The message can include special formatting, colors, or placeholders, making it useful for feedback, notifications, or announcements..
