Close only one window in Emacs

Question

In vim, a buffer can be divided horizontally or vertically into :sp or :vsp . And the buffer can be closed :q .

Similarly, in emacs, a window can be split horizontally at Cx 2 and vertically at Cx 3 . And close all other windows Cx 1 .

But how can I close only one window, for example :q in vim?

Answer 1

Try Cx 0 , delete-window . Here is what Ch k describes:

 (delete-window &optional WINDOW) Remove WINDOW from its frame. WINDOW defaults to the selected window. Return nil. Signal an error when WINDOW is the only window on its frame. 

Answer 2

There is a delete-window that is bound to Cx 0 by default.

Answer 3

You can do Ctrl - x 0 to close the current window, which is the default binding for delete-window
