Mac下全选，使用pynput，怎样调用command键？

Key.command 不行，用Key.cmd  。

win或linux下：
 

with keyboard.pressed(Key.ctrl):

    keyboard.press('a')

    time.sleep(1)

    keyboard.release('a')

那么在mac下就是：

with keyboard.pressed(Key.cmd):

    keyboard.press('a')

    time.sleep(1)

    keyboard.release('a')

因为mac下全选按钮是command + A
