In Terminal Emacs (no mouse), I'm using split windows to work with multiple buffers at the same time. I'm finding moving between the split windows much more painful than how I do it in Vim. Reading the documentation it looks like I'm doing it correctly (C-x o), but that just cycles around the windows in a clockwise direction. If I move to an adjacent window to make a quick edit, I need to hit C-x o a few times before I'm back where I was. Sometimes I accidentally press it too many times in a hurry and have to cycle all the way back through the windows again.
Far from install yet-another-external-package, is there any way I can just either move directly to a window (by, say, a number), or at least cycle around the windows in the opposite direction?
In Vim C-w C-w is like C-x o in Emacs, but there's also C-w ARROW to move in a specified direction... something like that? :)
Add this to your init file:
(windmove-default-keybindings)
Then you can use SHIFT+arrow to move to the next adjacent window in the specified direction.
You can specify a different modifier if you prefer, by passing an argument (defaults to 'shift).
Or just bind whatever you like to these functions:
windmove-up
windmove-down
windmove-left
windmove-right
You can also add FrameMove to the mix, to make this work transparently across multiple frames.
For numbered window navigation, there's switch-window.el.
Add this to your init file (e.g. ~/.emacs):
(windmove-default-keybindings)
Then do SHIFT+arrow to move to the window in that direction.
You can give a prefix argument to C-x o like this C-u -1 C-x o. This way you can go any number of windows forward or backward. Personally I think it's easier to create a special key for moving back one window. I have this in my .emacs:
(defun other-window-backward ()
"Goto previous window"
(interactive)
(other-window -1))
(global-set-key (kbd "\C-x p") 'other-window-backward)
I use the following to navigate to the next (same as C-x o), previous, first, and last window:
(defun my-previous-window ()
"Previous window"
(interactive)
(other-window -1))
(global-set-key "\C-xp" 'my-previous-window)
(global-set-key "\C-xn" 'other-window)
(defun my-select-first-window ()
(interactive)
(select-window (frame-first-window)))
(defun my-select-last-window ()
(interactive)
(select-window (previous-window (frame-first-window))))
(global-set-key "\C-x<" 'my-select-first-window)
(global-set-key "\C-x>" 'my-select-last-window)
Use window-jump, e.g.:
;; C-x <direction> to switch windows
(use-package window-jump
:bind (("C-x <up>" . window-jump-up)
("C-x <down>" . window-jump-down)
("C-x <left>" . window-jump-left)
("C-x <right>" . window-jump-right)))
For help with use-package, see https://github.com/jwiegley/use-package/blob/master/README.md.
For the sake of completion, there is window-numbering and ace-window too
I wrote an elisp module a while back to expand on windmove to make it a bit more useful: http://samograd.ca/stumpwm.el. You can bind stumpwm-move-window-[left/right/up/down] to whatever keys you want and the windows will move in the correct direction, even into another another frame (tested with 2 frames). There's also an stumpwm-interactive-resize-window for handy interactive window resizing using C-n/C-p/C-f/C-b with Return to end resizing.

Using Emacs 25 in a linux environment, I often copy text with the mouse and wish that I could paste the copied text with some command in Emacs, but currently the only way I know of is via the mouse middle click which is bound to mouse-yank-primary.
I've attempted to bind this to a key command, along with setting mouse-yank-at-point set true, but this (as I suspected) requires a mouse event to work correctly and I'm not sure how to get Emacs into believing that a mouse event went off due to a keystroke.
Anyone have any ideas? Or simply know the correct way to yank with the keyboard from the PRIMARY selection?
After looking around thanks to Christian's answer, I found select.el and came up with the following to stick into my .emacs
;; Pull from PRIMARY (same as middle mouse click)
(defun get-primary ()
(interactive)
(insert
(gui-get-primary-selection)))
(global-set-key "\C-c\C-y" 'get-primary)
Edit: As noted by Stefan, gui-get-primary-selection (and more generically, gui-get-selection) are only available in Emacs 25 and up. In Emacs 25.1 x-get-selection was made obsolete.
I just got annoyed by emacs default behavior of inserting the secondary X-selection on S-insert and found this thread. I tried to use the code from Silfheed but emacs 24 has no function like 'gui-get-primary-selection'. So I browsed the source for 'mouse-yank-primary' and came up with this alternative solution:
;; Pull from PRIMARY (same as middle mouse click)
(defun paste-primary-selection ()
(interactive)
(insert
(x-get-selection 'PRIMARY)))
(global-set-key (kbd "S-<insert>") 'paste-primary-selection)
So s-insert will insert the primary X-selection on the cursor position - just as in xterm...
Try setting this:
(setq select-enable-clipboard t)
this way the normal kill/yank commands (eg C-w and C-y) will work with the clipboard. Works both on X11 and OSX (and, I believe, Windows as well).
If you consult the documentation for that variable (for instance via C-h v) you should a sentence like this:
You can customize this variable.
where "customize" is a link you can click. This will bring you to Emacs' customaization system which provides an easier and more guided way of configuring Emacs. In particular, it will show you at lot about the controls that may be relevant to tweak. Even you do not want to control your confuguration that way, you can use it as guide to important variables to set and what they can be set to.
Hopefully this helps. It is shamelessly copied from above, but works both on 24 and 25. I have not tested in in other versions.
(if (< emacs-major-version 25)This w
;; in emacs 24 or previous
(defun paste-primary-selection ()
(interactive)
(insert (x-get-selection 'PRIMARY))
)
;; in emacs 25 and above
(defun paste-primary-selection ()
(interactive)
(insert (gui-get-primary-selection)))
)
(global-set-key (kbd "S-<insert>") 'paste-primary-selection)
How do I move the cursor directly here
without a mouse?
In your current situation, you can use M-minusC-xo, or press C-xo twice. C-xo invokes the other-window function which moves the cursor to the next window, prefixing it with - moves it to the previous one.
This is a better way to select the minibuffer, regardless from where your point is set now, and won't do anything when there actually is no minibuffer.
I actually copied the answer (since this is a duplicate question) from Trey Jackson
(defun switch-to-minibuffer-window ()
"switch to minibuffer window (if active)"
(interactive)
(when (active-minibuffer-window)
(select-window (active-minibuffer-window))))
(global-set-key (kbd "<f7>") 'switch-to-minibuffer-window)
If you enable (windmove-default-keybindings) then you can select the minibuffer simply by typing S-<down> (to switch to the window below the one you're in) as many times as necessary.
if I want to change windows in emacs I do C-x o and that's fine with me...but when I want to change window lots of times in a row C-x o is not so convenient...is there a way to change window with just one strike after first C-x o ?
and in general...is there a (single) strike that would repeat my last shortcut?
I use C-tab to switch windows:
(global-set-key [C-tab] 'other-window)
Holding down the Control key, you can jump windows repeatedly just by hitting the tab key.
EDIT: my original answer contained the following
I don't think there's a built-in way to repeat last command for basic commands like this ...
This is no longer true. Emacs now contains repeat.el, which allows for exactly the behaviour rabidmachine9 asked for.
The following code will create a repeating other-window, such that after pressing C-x o the first time, pressing o afterwards will continue moving to the next window.
(require 'repeat)
(defun make-repeatable-command (cmd)
"Returns a new command that is a repeatable version of CMD.
The new command is named CMD-repeat. CMD should be a quoted
command.
This allows you to bind the command to a compound keystroke and
repeat it with just the final key. For example:
(global-set-key (kbd \"C-c a\") (make-repeatable-command 'foo))
will create a new command called foo-repeat. Typing C-c a will
just invoke foo. Typing C-c a a a will invoke foo three times,
and so on.
See related discussion here:

https://groups.google.com/forum/?hl=en&fromgroups=#!topic/gnu.emacs.help/RHKP2gjx7I8"
(fset (intern (concat (symbol-name cmd) "-repeat"))
`(lambda ,(help-function-arglist cmd) ;; arg list
,(format "A repeatable version of `%s'." (symbol-name cmd)) ;; doc string
,(interactive-form cmd) ;; interactive form
;; see also repeat-message-function
(setq last-repeatable-command ',cmd)
(repeat nil)))
(intern (concat (symbol-name cmd) "-repeat")))
(global-set-key (kbd "C-x o") (make-repeatable-command 'other-window))
The function make-repeatable-command than then be used to create other repeating commands, using the same template.
Check out windmove; it lets you just hold down a modifier key and press an arrow key to move to the window in that direction. I've been using it for years with the default modifier (shift) and strangely enough it doesn't interfere with my impulses to use shift-arrow text selection in other applications.
There's also an equivalent for frames, which I should really try...
You have, say, 10 windows in the frame, and you are doing M-x other-window a lots of times in a row, I take it you mean to jump from, say window #2 to window #8 and then on to window #1 and so on. By doing lots of other-window in a row, I would imagine you do nothing of importance until you reach the desired window.
See if universal-argument bound to C-u helps. In the 10 window frame, if you are in window #3 and want to go to window #9, you are hopping to the 6th next window. So you would do C-u 6 C-x o. Or, you could as well do C-u -4 C-x o and reach window #9 from window #3.
Bit late to the party, but there is also window-numbering (known as 'window-number' in MELPA).
This includes a window number in the modeline -1-, -2- etc, and provides M-1, M-2 etc key bindings to directly select them. Very quick.
Not being using Emacs all that long (v23, windows) and just discovered M-x ediff. Fantastic.
Although I'm not to keen on the fact it opens its help/navigation in a separate frame/window, meaning that if I lose focus to that window, the single key shortcuts don't work.
For example as soon as I press ? to expand the window, it shifts over top of my current window, so I have to pick up my mouse and move it to another screen. Then if I lose focus to that window and press p / n / j or any other key to work with the diff, it inserts it into my document. So i have to undo, grab mouse, focus to other window, and repeat.
Is there any way to configure these options to show in a split instead?
I didn't know how to do it but it is usually easy to learn with Emacs. First I asked about ediff customizations:
M-x customize-apropos
ediff
I saw there is something called Ediff Window Setup Function which takes the values Multi Frame, Single Frame, or Other Function. Mine was set to Multi Frame and changed it to Single Frame and saved it for future sessions. And Voila! as they say somewhere.
Simply:
(setq ediff-window-setup-function 'ediff-setup-windows-plain)
M-x describe-variable ediff-window-setup-function will enlighten you
further.
For reference my ediff customisation is fairly simple:
(if (locate-library "ediff")
(progn
(autoload 'ediff-files "ediff")
(autoload 'ediff-buffers "ediff")
(eval-after-load "ediff" '(progn
(message "doing ediff customisation")
(setq diff-switches "-u"
ediff-custom-diff-options "-U3"
ediff-split-window-function 'split-window-horizontally
ediff-window-setup-function 'ediff-setup-windows-plain)
(add-hook 'ediff-startup-hook 'ediff-toggle-wide-display)
(add-hook 'ediff-cleanup-hook 'ediff-toggle-wide-display)
(add-hook 'ediff-suspend-hook 'ediff-toggle-wide-display)))))
From chapter Window and Frame Configuration in Ediff User's Manual:
The following variable controls how
windows are set up:
ediff-window-setup-function
The multiframe setup is done by the ediff-setup-windows-multiframe
function, which is the default on
windowing displays. The plain setup,
one where all windows are always in
one frame, is done by
ediff-setup-windows-plain, which is
the default on a non-windowing display
(or in an xterm window). In fact,
under Emacs, you can switch freely
between these two setups by executing
the command ediff-toggle-multiframe
using the Minibuffer of the Menubar.
(custom-set-variables
...
'(ediff-window-setup-function (quote ediff-setup-windows-plain))
...)
Not that you would set the variable this way, but it allows you to know these things:
The variable you are interested in is ediff-window-setup-function
The value it needs to be set to is ediff-setup-windows-plain
You can configure the variable from customize: M-x customize-group RET ediff-window
Ediff Window Setup Function: Menu Single Frame
Note: you can avoid using the mouse to go back to the ediff control window by using M-x other-frame. Also found on C-x 5 o.
This no longer works in 2017 gnu emacs (24.5, 25.2, 2017) on windows
(setq ediff-window-setup-function 'ediff-setup-windows-plain) ; stopped working
Even
ediff-toggle-multiframe ; no longer has any effect now.
It works in emacs22.3 on windows, so I have use older emacs from 2008!
This is probably a very naive Emacs question - I'm new to it.
When I'm evaluating a lisp expression, if there's an error the debugger automatically comes up in another window. If I have *scratch* and *info* open (the former for trying out lisp and the latter for reading about it), then the debugger opens up in the window that *info* was in. At the moment, I have to switch to that window, then change it back to *info*, before returning to *scratch*. (The same thing happens if I do C-x C-b for a list of buffers.) I'm guessing there has to be a way to just close that window without this long sequence of commands. Can anyone enlighten me?
At least here on my emacs (22.3), when the debugger pops up, its window becomes the active one. There, pressing q just quits the debugger, if that's what you want. At that point, it also gets out of recursive editing.
From what I understand, you want to close the buffer in the other window without moving your cursor from the current window.
I don't any existing function does that, so I rolled my own.
(defun other-window-kill-buffer ()
"Kill the buffer in the other window"
(interactive)
;; Window selection is used because point goes to a different window
;; if more than 2 windows are present
(let ((win-curr (selected-window))
(win-other (next-window)))
(select-window win-other)
(kill-this-buffer)
(select-window win-curr)))
You can bind it to something like "C-x K" or some other somewhat difficult-to-press key so you won't press it by mistake.
(global-set-key (kbd "C-x K") 'other-window-kill-buffer)
I use this a LOT! (for Help buffers, Compilation buffers, Grep buffers, and just plain old buffers I want to close now, without moving the point)
I'm usually using the delete-other-windows command. C-x 1.
It's so regullar, that I rebinded to F4.
Official docs: https://www.gnu.org/software/emacs/manual/html_node/emacs/Change-Window.html#Change-Window
HTH
Using winner mode, you can use the keybinding C-C left arrow to return to the previous window configuration. Of course, this doesn't actually kill the new buffer, but it does hide it.
I think you're looking for C-x 4 C-o, which displays a buffer in the "other" window without switching to it.
As mentioned above, in the case of the backtrace buffer you probably want to exit from it with q, to get out of the recursive edit.
Try to use popwin-mode. It is really good about closing windows automatically.
I want to describe how mechanism work|
You open undo-tree-visualize than you find your correct branch, after that when you change your active window which has cursor via switch-window undo-tree related buffer will close other window automatically.
One possible solution is to use a window management package. Store your "preferred" window arrangement, and after the debugger/buffer window pops up and you're done with it, revert to your preferred arrangement.
There are a bunch of packages to choose from, see: switching window configurations on the wiki.
Additionally, you might want to figure out the actions you commonly do that trigger the extra (unwanted) window popping up, and use that to trigger saving your window configuration just before the window pops up.
If you want to roll your own (it's pretty easy), you can just save off the window configuration, and restore it like so:
(setq the-window-configuration-i-want (current-window-configuration))
(global-set-key (kbd "<f7>")
(lambda () (interactive)
(set-window-configuration the-window-configuration-i-want)))
The trick is figuring out where to put the setting of the-window-configuration-i-want.
Thanks go to #spk for a nice function. I merely modified it to also close the window too and bound it to the already nice set of window control functions found in evil-windows (via "C-w"):
(use-package evil
:bind (:map evil-window-map ("O" . delete-most-recent-window))
:preface
(defun delete-most-recent-window ()
"Kill the buffer in the most recent window."
(interactive)
;; Window selection is used because point goes to a different window
;; if more than 2 windows are present
(let ((win-curr (selected-window))
(win-other (next-window)))
(select-window win-other)
(kill-this-buffer)
(delete-window) ; <-- Added this
(select-window win-curr))))
