macos: alt-tab not ... alt tabbing?

[ldemailly]

Is that a limitation of the OS or my mistake but alt-tab seems to do nothing:

		kb.Clear()
		kb.SetKeys(keybd_event.VK_TAB)
		kb.HasALT(true)
		err := kb.Launching()

Same with .Press() .Release()

meanwhile I found this workaround but it's... not great

cmd := exec.Command("osascript", "-e", `tell application "System Events" to keystroke tab using command down`)
err := cmd.Run()
