Very interesting question indeed.

I've read the win32com docs (http://timgolden.me.uk/pywin32-docs/html/com/win32com/HTML/QuickStartClientCom.html#Using) and I figured out that the module does not seem to implement a listener for key presses.

However, a possible solution for your problem consists in using win32gui and pynput modules like this:

import win32gui
from pynput import keyboard

def on_press(key):
     try: key_pressed = key.char # single-char keys
     except: key_pressed = key.name # other keys
     print(key_pressed)
     active_window = win32gui.GetWindowText(win32gui.GetForegroundWindow())
     print(active_window)
      
listener = keyboard.Listener(on_press=on_press)
listener.start() 
listener.join() 

The keyboard listener handles the key press event, whereas win32gui gives you the active window name at the time of key press.

Of course, you can then easily filter by the window that you're interested in:

def on_press(key):
 try: key_pressed = key.char # single-char keys
 except: key_pressed = key.name # other keys
 active_window = win32gui.GetWindowText(win32gui.GetForegroundWindow())
 if active_window == "Youtube - Google Chrome":
      # ... 
      # do something
      # ...
