Emacs has the function kill-buffer-and-window mapped to C-x 4 0. Naturally, I expected C-x 4 1 to select the other window, kill the buffer and delete the window. I find myself using C-x o followed by C-x 4 0 a lot, which is very tedious. The q command for closing *Help* windows still leaves the buffer open.
Is there a function that has the expected behaviour of kill-other-buffer-and-window ?
