Is there a way to undo split-window-below in emacs?

Question

If I have my frame split horizontally, then split one of those widows vertically with split-window-below, is there a way to go back to 2 windows split horizontally without having to use delete-other-windows and then split-window-right?

Accepted Answer

You can use `delete-window` which is bound to `C-x 0`.
