In Backrooms Motion on Roblox, the control shown for dropping items is Backspace , not a separate throw key. The game page does not show a dedicated throw command, so if you’re trying to move an item in front of you, it may only support dropping items rather than true throwing.

What to try

  • Open your inventory with B and select the item first.
  • Use Backspace to drop it.
  • If the game has a specific item-throw animation or mechanic, it is likely tied to that item’s own behavior rather than a universal control, since the public controls list does not mention throwing.

If it still won’t work

  • The item may be non-throwable in the current version, especially since the game is still marked as in development and may change or have bugs.
  • Some Roblox games treat “throwing” as a special item action, so the item itself may need to be equipped or used in a certain way rather than pressed with a general key.

Quick takeaway

For this game, the safest answer is: use Backspace to drop items, and there may not be a normal throw feature available.
