In the [Deck] properties, there’s an entry for “Include command to send entire deck to another deck”. You can set up a specific key for each deck. When selected, you can add information to create a menu button, if you like, and a hot key.
Since the hot key you’re applying to this deck is a global hot key, if you wish to use a game component to perform this action (card, button, etc), then you can use a Global Hotkey trait on that component to trigger the movement of the deck.
If you wish to move several decks at once, you would use a Trigger Action trait to fire several Global Hotkeys …one hotkey for each each deck.
Example based on your description:
DeckA [Deck]
DeckB [Deck] (Include command to send entire deck to another deck) - Checked
Send Hotkey - ALT B
Name of deck to send to - DeckA
DeckC [Deck](Include command to send entire deck to another deck) - Checked
Send Hotkey - ALT C
Name of deck to send to - DeckB
DeckD [Deck](Include command to send entire deck to another deck) - Checked
Send Hotkey - ALT D
Name of deck to send to - DeckC
Let’s say you’re using a game piece set up as a button to trigger the deck switches. Your game piece would have the following traits. Keep in mind that I’m listing them in the order they would execute but traits in a game piece operate from the bottom up. So, the first item listed here would the last item in your trait list on the piece.
Action Button
Fires - CTRL 1
Trigger Action
Keystroke - CTRL 1
Perform these keystrokes
CTRL B
CTRL C
CTRL D
Global Hotkey
Keyboard Command - CTRL B
Global Hotkey - ALT B
Global Hotkey
Keyboard Command - CTRL C
Global Hotkey - ALT C
Global Hotkey
Keyboard Command - CTRL D
Global Hotkey - ALT D
This should send DeckB to DeckA, then DeckC to DeckB, then DeckD to DeckC.
