Unknown Trick. Ctrl + MMB to change ortho/perspective

So I have been surprising various Unreal users for a while about this trick I stumbled upon, since it seems to be totally undocumented and never spoken off, and I wanted to share it around.

Did you know you can hold Ctrl+MMB down, and move the cursor to the direction you want the orthographic view to jump too? Random but very cool little shortcut.
