Details panel isn't showing

I accidentally pressed the “close” button on the details panel and now I don’t know how to get it back…
Any help would be great!
P.S.: I’m new with Unreal Engine 4 and I’m a little bit confused… Sorry for that :frowning:

All main tabs toggles are in “Window” menu, in fact you can open 4 “Details” tabs :stuck_out_tongue:
