Texture Space Question

I am wondering what gives with the texture space selection in the Object Data Properties area of 2.8. I can clearly change the size of my texture space but it doesn’t seem to affect the texture that is applied. I used to be able to alter the shape of my texture’s XYZ in 2.79 and the texture would change accordingly. Also, it seems the Shift Alt T shortcut for selecting the texture space doesn’t work like it did in 2.79. Any ideas?
