thanks a lot for posting your solution here.

you'll need to install these packages to your c4d installation to make it work

import win32gui
import win32ui
import win32co
from pynput.keyboard import Key, Controller
handle = win32gui.FindWindow(0, "Texture Manager")
    try:
        if handle:
            
            keyboard = Controller()    
            win32gui.SetForegroundWindow(handle)
            keyboard.press(Key.ctrl)
            keyboard.press(w)

            keyboard.release(Key.ctrl)   
            keyboard.press(w)
    except:
        pass

this thread will be considered solved and will be closed tomorrow if you have nothing to add.

That's because there is none. The Windows functionality in the API is very limited. You can open some through CallCommand but identification and handling of specific windows is not supported.

Only thing you could do is loading a new layout.

I was afraid of that answer
But thank you anyway
