Stream Deck macro keypad

I suppose if somebody is a Dorico ninja, and is able to memorize every key combination, that is the fastest way to work. But I see a lot of merit in having this separate device:

  1. It is visual
  2. You can organize the buttons in ways that are logical to how you work.
  3. I am taking a leap here, but I think it might help with one of my biggest frustrations, which is juggling two applications. I often run a program called Transcribe! alongside Dorico. Transcribe is a convenient way to listen to music fragments I might be putting into notation. But when using the PC keyboard in invariably try to type commands into the app I am LOOKING at rather than the app that has focus. If the Stream Deck can respond to the app that has focus, that would reduce this problem. Better yet, if Stream Deck can send command to an app that is out of focus, then the problem could be solved completely.

Is it possible to have two of these Stream Decks installed and active on the same computer?
