Yes, you can use keyboard shortcuts to control deck players in PlayIt Live. You can configure custom keyboard shortcuts for various PlayIt Live actions including deck player controls through the keyboard settings.

To set up keyboard shortcuts, go to File > Settings and click on the Keyboard tab. Select a command from the keyboard binding list that you want to assign a shortcut to, then click in the key field and press your desired key combination. For example, you could set Ctrl+1 to play deck 1 or Ctrl+2 to play deck 2.

If you want your keyboard shortcuts to work even when PlayIt Live doesn't have focus (such as with external controllers like Stream Deck), make sure to tick the Global trigger checkbox at the bottom of the keyboard settings section. This ensures your shortcuts work when PlayIt Live is running in the background.
