In JJBA: DIAMOND , the keybind menu is opened with ;. The game’s listed controls also show C to summon your stand, G to grab/throw debris, R for remote stand control, and F to move your user to the cursor while remote-controlling.

If you mean “drop” as in putting down or releasing an item, the game page does not show a dedicated drop key in the visible controls list. The safest move is to open the keybind menu with ; and check whether drop is mapped there or needs to be assigned manually.

Quick input list

  • ; = Open keybinds menu
  • C = Summon stand
  • G = Grab/Throw debris
  • R = Toggle remote-stand-control
  • F = Move user to cursor in remote control

If the bind seems missing

Some Roblox games hide or customize controls, so if you do not see a drop option, it may be unavailable in that mode or tied to a specific item rather than a universal keybind. A quick test is to open the menu, look for any “drop,” “release,” or “throw” action, and rebind it from there.

TL;DR: press ; for keybinds, then look for the drop/release action; the visible default controls do not list a separate drop key.
