Duplicating objects

How do you duplication objects in the scene? As the only videos I can find are in older version of UE4 and the all say to select the object and press alt. Then slide the new object out but, alt just moves the camera. what key do I press to duplicate or what I am doing wrong?

In the blueprint editor viewport you will need to press Ctrl+W after selecting the mesh you want to duplicate.

The Alt method still works too. First select the object and press ‘W’ to make sure that Translate mode is being used (should see 3 colored arrows coming from the center of the object). Then, while holding Alt, click and drag on any of the 3 arrows.
