Is there any keybinding or function to move an open buffer to a different window or a different frame in spacemacs?

2 Answers 2


It seems key bindings have been changed in Spacemacs since @Nathanael's answer.

To move a buffer to a diffferent window, you can use SPC b [n] (buffer-to-window-[n]), where n is the number of the window to move to.

If you want to move the window , rather than the buffer (which makes sense in the light of the comments given above):

SPC w [H|J|K|L]

to move the window left|down|up|right, respectively.

  • Thanks for the answer! The final sentence is the actual answer to the question (and what I came here looking for), and I very nearly missed it. Might be worth moving it to the top or calling it out better. :)

In spacemacs (vim mode) you can press SPC b m <your-direction> to move a buffer. <your-direction> can be:

  • h left
  • j down
  • k up
  • l right

In emacs mode, it should be M-m b m <your-direction>

If you want to switch to the 'other' frame, you can use SPC b M (or M-m b M).

(In general, Emacs places no restriction on the number of windows/frames a buffer is displayed in, so you can simply switch to the buffer in however many windows/frames you want.)

  • and is it possible to move the buffer to a different frame? (ideal would be something comparable to ace-window to select the target window and frame)

    You can just switch to the buffer when you are in the other frame, not sure if there's a native spacemacs way to do this though. Commented Feb 3, 2016 at 11:58

    Perhaps to clarify, what I am looking for: I have a buffer open in one window want to open it in a different window and frame while closing it in the current one, so that I have the buffer open only in the target window and frame after the move

    Perhaps you need something like SPC b M which puts the current buffer in the 'other' frame, then C-x 5 1 to remove all other frames? Commented Feb 3, 2016 at 12:04

    I'm not sure if this is still valid — could these commands have changed because when I try to use SPC b m (or look at commands available in buffer mode) it gives the option to kill buffers (specifically spacemacs/kill-other-buffers), and does not offer to move the current buffer. SPC b M seems to be unmapped to any specific command and is remapped to SPC b m which is as before spacemacs/kill-other-buffers. There is a move buffer to window command but it doesn't seem to be mapped to anything in particular. I don't see anything about frames.
