Numpad key 4 and 6 not working

Hi guy’s, the numpad key 4&6 for orthographic left and right view is not working, it give me perspective view both of them!

Any clue and i have already activate emulate numpad and it’s still the same?

Never mind i figure it out, i was following a pdf with all blender shortcuts and it was not updated to most recent version.

For those who have the same issue right ortho is 3 and left ortho is 9. Handy little feature is that you can control object movement with key 4,8,6,2 while holding ctrl.
