After watching some Minecraft Java Edition videos I realized that there are plenty of controls not implemented, or not explained, in Minecraft Bedrock for PS4. For example...
In the inventory:
: Quickly moves a block/item into its appropriate space, of between inventory and hotbar : Take half of the highlighted stack : Place one item from a stack in a slot (hold and drag): Place one item from a stack in each inventory slot Double: Sort loose highlighted items into one stack
From the hotbar:
(R2): Wear/switch highlighted piece of armor from the hotbar
