Emacs merging buffers into one without using C-x 1 keybind

Question

Could you suggest the key bind in emacs to do the following:

Steps: for example 1) I divided all text editor area into 2 pieces with command C-x 2 2) Then I divided first one on another 2 pieces with C-x 3 3) How can I make the first piece (a buffer in this case)

Answer 1

If i understand you correctly you want to C-x 0 in the window you want to close.

Answer 2

The interactive solution is to put the cursor in the bottom buffer and hit C-x 0.

Answer 3

the other option if you enjoy using the mouse is to right click on the modeline of the buffer you want to close (the one which shows helpers.py in your screenshot). The only thing which you have to note is that you should not click on the file name, as right click on file name is bind to switch buffer by default.

Answer 4

C-x 0 did the trick
