Preview Scene Script

Hello Dears,
I use use Streamer.Bot/Noob Commander and HID Macros to create a keyboard with shortcuts to ease the use of OBS with a 10 cam setup.
Simply I create .vbs or .bat file that do a specific task on obs using Streamer.Bot or Noob Commander and assign it to a key on a second keyboard using HIDMacros. My problem is that while using Studio Mode, I can't find a command to change the preview scene. I searched OBS documentation but unfortunately I didn't find anything (maybe because I didn't understant a lot :D). So I would be glad if someone guided me with a script or command to change preview scene.
Thanks in advance

If with "change preview scene" you mean you want to transition the output to the currently showed preview in studio mode, assign a hotkey to the "Transition" action in Settings->Hotkeys. This will act as if you press the "Transition" button.
