Just like Ctl, Alt + delete
I want to write a program, which uses global hotkeys with 3 or more arguments in python. The assigned function should only perform when I press all three keys on my keyboard. For example alt, windows and F3.
win32con.VK_F3, win32con.MOD_WIN, win32con.VK_F5
This is the current program I want to run, however its output is:
Traceback (most recent call last):
File "C:Python32Syntaxhot keyshotkeys2.py", line 41, in <module>

ValueError: too many values to unpack (expected 2)
The Program:

3 : handle_win_f1_escape
}
for id, (vk, modifiers) in HOTKEYS.items ():
print ("Registering id", id, "for key", vk)
if not user32.RegisterHotKey (None, id, modifiers, vk):
print ("Unable to register id", id)
try:
msg = wintypes.MSG ()
while user32.GetMessageA (byref (msg), None, 0, 0) != 0:
if msg.message == win32con.WM_HOTKEY:
action_to_take = HOTKEY_ACTIONS.get (msg.wParam)
#print(" msg.message == win32con.WM_HOTKEY:")
if action_to_take:
action_to_take ()
user32.TranslateMessage (byref (msg))
user32.DispatchMessageA (byref (msg))
finally:
for id in HOTKEYS.keys ():
user32.UnregisterHotKey (None, id)
print("user32.UnregisterHotKey (None, id)")
Registering 3 hotkeys? Possible?
Explains how one can use assign one key that needs to be pressed and then if two of which either needs to be pressed. However I won’t that the function only performs when all there are pressed simultaneously. I took
