SDL Studio 2017 - by mistake weblookup clicked away, how to integrate it again in the SDL Studio windows on the bottom?

I hope someone knows how to do this! This is the second time that this happens to me in several weeks, but I don't recall in any way how the window was to restore again. And I need this window absolutely below!

Unfortunately the new layout of software in general is not very user friendly and logical.

Thanks in advance
