Change foreground and background node inputs CTRL+T

Just a quick tip I just found out.

If you connect nodes into a merge node (for example) wrong way and you need to switch foreground and background inputs you can do it by selecting the merge node and hitting CTRL+T

I'm afraid that doesn't work for me.

As usual, Command+T on Mac.

I hope he was being facetious or I hope at least one of them was.
