awesome wm - Simultaneously switch tags as one screen in multi monitor setup in 3.5?

The answer propsed in Simultaneously switch tags as one screen in multi monitor setup

is not working in awesome 3.5. Any solutions?

Since I' m new to awesome and lua, I don' t know how to do it myself. And I have no right to comment on the anwser. Sorry for restarting a question.

Answer

awful.key({ modkey, "Control"   }, "Left", 
function()
    for i = 1, screen.count() do
        awful.tag.viewprev(i)
    end
end ),

awful.key({ modkey, "Control"   }, "Right", 
function()
    for i = 1, screen.count() do
        awful.tag.viewnext(i)
    end
end ),
