oAutoItX.Opt("WinTitleMatchMode", 2) #Match text anywhere in a window title

width = oAutoItX.WinGetClientSizeWidth("Firefox")
height = oAutoItX.WinGetClientSizeHeight("Firefox")

commands = [command for command in vs.Commands if bool(command.Name) or bool(command.Bindings)]
commands.sort(key=lambda cmd : cmd.Name)
