When I used emacs, I used to be able to set the mark and highlight full pages for yanking using C-v, or scroll-up. However, in Aquamacs if I set the mark then hit C-v it loses the mark and stops highlighting. I noticed that in Aquamacs C-v is instead mapped to aquamacs-page-down, so I tried adding the following command to my site file:
(define-key osx-key-mode-map "C-v" 'scroll-up)
and this didn't successfully remap the key. I then tried something similar:
(define-key global-map "\C-v" 'scroll-up)
and still nothing. Aquamacs very stubbornly hangs onto the mapping to aquamacs-page-down. I noticed, however, that there's an additional function, aquamacs-page-down-extend-region, which does exactly what I'm talking about. Its key sequence, however, is , and I have no idea how to input that. I tried "shift-control-v" to no avail.
Has anyone been able to get Aquamacs to scroll pages while maintaining the mark?
I've found a way to get this to work, for posterity's sake.
Paste this into the .emacs file:
;; Enable scrolling to maintain mark if set
(defun scroll-down-maintain-mark ()
(interactive)
(if mark-active
(aquamacs-page-down-extend-region)
(aquamacs-page-down)))
(defun scroll-up-maintain-mark ()
(interactive)
(if mark-active
(aquamacs-page-up-extend-region)
(aquamacs-page-up)))
(define-key global-map "\C-v" #'scroll-down-maintain-mark)
(define-key global-map "\M-v" #'scroll-up-maintain-mark)
hitting C-SPC C-v C-l, the last to recenter screen, seems to show that it does indeed preserve the mark.
and subsequent copy and yank works fine
perhaps this behavior added on newer Aquamacs.

I am trying to make toggle insert/normal mode in evil in spacemacs.
I have successfully accomplished that with code down there. But LED light next to Caps-lock on my macbook pro 2018 13' stoped working. So i am trying to switch led on my caps-lock with script.
I am using karabiner-elements to remap caps-lock to f13. When emacs records f13 it changes state to evil-normal-state or evil-insert-state.
The problem starts, when i want to add another command to run when f13 aka caps-lock ist pressed. Its (shell-command "/Users/atrumoram/setleds +caps"). Which turns the light on caps-lock or turns it off. I was trying to make my own function defun. But i really cannot make it work together. In the end i would like to have something like this.
This is code that toggles insert/normal mode in evil using capslock
(define-key evil-insert-state-map (kbd "<f13>") 'evil-normal-state)
(define-key evil-normal-state-map (kbd "<f13>") 'evil-insert-state)
In the end i would like to have something like this.
(define-key evil-insert-state-map (kbd "<f13>") 'evil-normal-state (shell-command "/Users/atrumoram/setleds +caps"))
(define-key evil-normal-state-map (kbd "<f13>") 'evil-insert-state (shell-command "/Users/atrumoram/setleds -caps"))
Is there some way somebody can help me out? Looking forward for your ideas.
A key can only be bound to one function at a time, so in order for two things to happen when you press the key, you need to create a function, make it "interactive", and bind that to the key you want.
This function performs the two actions, one after the other:
(defun my-evil-normal-state-and-set-caps-led ()
(interactive)
(evil-normal-state)
(shell-command "/Users/atrumoram/setleds +caps"))
Since it's declared as an interactive function, you can test it with M-x my-evil-normal-state-and-set-caps-led.
Then it's just a matter of:
(define-key evil-insert-state-map (kbd "<f13>") 'my-evil-normal-state-and-set-caps-led)
And vice versa for switching to insert state.
I am using the mac emacs from http://emacsformacosx.com/, and I need to click the maximized icon when I start my emacs.
How can I set the maximized emacs window as default?
start emacs like this
emacs -mm
Ryan McGeary's maxframe.el works well for me on both Aquamacs and Emacs.app. I found it through EmacsWiki: http://www.emacswiki.org/emacs/FullScreen . That page talks about a patched version which is now a 404 page, but the original one at https://github.com/rmm5t/maxframe.el seems to work fine.
Here is a function written and used by me. When you succesivelly press F11, emacs switches in 4 modes:
(defun switch-fullscreen nil
(interactive)
(let* ((modes '(nil fullboth fullwidth fullheight))
(cm (cdr (assoc 'fullscreen (frame-parameters) ) ) )
(next (cadr (member cm modes) ) ) )
(modify-frame-parameters
(selected-frame)
(list (cons 'fullscreen next)))))
(define-key global-map [f11] 'switch-fullscreen)
The short answer is to add the following to your custom-set-variables:-
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
...
'(initial-frame-alist (quote ((fullscreen . maximized))))
...
)
Given below is what I wanted as a solution to the same problem. TL;DR.
I face the same problem but in all applications and not just in Emacs. To this end, I have globally bound the shortcut key cmd-m on my Mac to the Zoom menu option which is usually the menu option for the green maximize button. Emacs however doesn't provide the Zoom menu option which is usually under the Window menu item. So I ended up with the following.
I just coded up the following last night.
;; This defines cmd-m to do the same as clicking the green titlebar button
;; usually meant for the "Window -> Zoom" menu option in Mac apps
(defun zoom () "zoom, same as clicking the green titlebar button in Mac app windows"
(interactive)
(set-frame-parameter
nil 'fullscreen
(pcase (frame-parameter nil 'fullscreen)
(`nil 'fullheight)
(`fullheight 'maximized)
(`fullboth (ding) 'fullboth)
(`fullscreen (ding) 'fullscreen)
(_ nil))))
(global-set-key (kbd "s-m") 'zoom)
This keyboard shortcut in the last line of the code goes well with my global to Mac cmd+m key binding that I described initially. You could customize it to whatever suits you. I am used to pressing cmd-m on launching most apps until it fits screen and Emacs is one of them for me. So I don't bother with the initial-frame-alist setting.
I went on to complete the feature-set I wanted by adding the following code tonight.
;; This defines ctrl-cmd-f to do the same as clicking the toggle-fullscreen titlebar
;; icon usually meant for the "View -> Enter/Exit Full Screen" menu option in
;; Mac apps
(defun toggle-fullscreen() "toggle-fullscreen, same as clicking the
corresponding titlebar icon in the right hand corner of Mac app windows"
(interactive)
(set-frame-parameter
nil 'fullscreen
(pcase (frame-parameter nil 'fullscreen)
(`fullboth nil)
(`fullscreen nil)
(_ 'fullscreen))))
(global-set-key (kbd "C-s-f") 'toggle-fullscreen)
; For some weird reason C-s-f only means right cmd key!
(global-set-key (kbd "<C-s-268632070>") 'toggle-fullscreen)
A couple of notes:-
If you're just learning to use pcase from this code, be careful not to make the same mistake as I did by misreading the backquote as a quote in the docs.
fullscreen is an alias to fullboth and is not a misnomer like the latter is as a term for what it means and hence I have not only handled that case as a value for (frame-parameter nil 'fullscreen) but use that whenever I want to set-frame-parameter to fullboth
HTH
The answer given at https://stackoverflow.com/a/1029065/351716 works for me (with GNU Emacs v24.2.1). To reprise, define the following function in your .emacs file:
(defun x11-maximize-frame ()
"Maximize the current frame (to full screen)"
(interactive)
(x-send-client-message nil 0 nil "_NET_WM_STATE" 32 '(2 "_NET_WM_STATE_MAXIMIZED_HORZ" 0))
(x-send-client-message nil 0 nil "_NET_WM_STATE" 32 '(2 "_NET_WM_STATE_MAXIMIZED_VERT" 0)))
For convenience, you can bind the command to a key. I use the C-z key, which would otherwise minimize the frame, which I have no need for, but always find annoying when I hit it accidentally:
(global-set-key (kbd "C-z") 'x11-maximize-frame)
As I noted in the comment I added to that answer, using this command repeatedly cycles between the normal frame state and the maximized state, but one little annoyance: in between those two, there's a strange state where the frame is almost but not quite vertically maximized. But that's a minor problem.
I have a Mac Laptop and I am connecting to server running Linux. As Alt+3 is already bound in EMACS to a command, so I cannot insert the hash symbol in a file.
I have tried the following solution I found online:
(global-unset-key (kbd "C-3"))
(global-set-key (kbd "C-3") '(lambda() (interactive) (insert-string
"#"))) //I know that C is for CTRL not Alt - I have tried with
M-3 instead as well
and some others as well, but none seem to work. Can you tell me any
other way in which I might be able to enter the hash sign (#) in a
file.
Aso tried (did not work):
(fset 'insertPound "#")
(global-set-key (kbd "M-3") 'insertPound)
Thank you!
From http://jimbarritt.com/non-random/2010/11/07/typing-the-pound-or-hash-key-in-emacs-on-uk-macbook
Typing the pound, or hash (#) key in emacs on UK Macbook:
The problem with OS X and the UK keyboard is that the pound key actually has a £ on it. To get “#” you have to press Alt+3
Of course, in emacs, the alt key is the meta key which is trapped by emacs. The simple function below inserted into your .emacs file should map the keys correctly.
;; Allow hash to be entered
(global-set-key (kbd "M-3") '(lambda () (interactive) (insert "#")))
I assume that you have a Mac UK keyboard so Shift-3 is £. On most other keyboards Shift-3 is # as others have said.
The way I get round it is to change the input source to Australian the only difference is that Shift-3 is now # and Alt-3 is £ (or leave as the emacs binding)
Input Source setting
was System Preferences->Language&text->Input Source
On later OSX versions (OSX 10.11 definitely but would have been earlier) Input Source setting is System Preferences->Keyboard->Input Source By default this will just show the UK keyboard to see more hit the + at the bottom of the list and add Australian
The reason I prefer this rather than adding code in emacs is that Shift-3 is # for all apps e.g. including Xcode/Eclipse so I don't have to switch the key according to the app or according to wether I am on a US keyboard or on Windows/Linux etc.
I know this is a bit late and the answer has been accepted. However, I have just moved from Linux to MacOS with a UK keyboard and had the same problem.
Note: I am using the emacs from here: http://emacsformacosx.com/. The below may be different for Carbon Emacs/Aquamacs etc.
The global-set-key method above is fine if you just need the # sign, but what if you also need to access the € character? (Which is Alt-3 on a UK keyboard)
The solution for me was to add this to my init file:
(setq ns-right-alternate-modifier (quote none))
This removes the emacs bindings for the right alt/option key.
You can see all the available options with
M-x customize-group RET ns RET

A lot of the solutions given here and elsewhere work for typing # in a normal buffer, but they don't make it work like a normal keypress; in particular, it will abort an incremental search, which makes it hard to write macros that deal with Python comments, or C #includes, for example. So, it's best to transform the key much earlier, so it just acts like another typing keystroke.
I've found that adding this command to your Emacs configuration works very well:
(define-key key-translation-map (kbd "M-3") (kbd "#"))
...and remove all the (global-set-key...) attempts.
If -- like me -- you switch your modifier keys around, Opt ⌥ is mapped to Hyper, so I just go belt-and-braces with:
(define-key key-translation-map (kbd "M-3") (kbd "#"))
(define-key key-translation-map (kbd "M-£") (kbd "#"))
(define-key key-translation-map (kbd "H-3") (kbd "#"))
(define-key key-translation-map (kbd "H-£") (kbd "#"))
(define-key key-translation-map (kbd "S-3") (kbd "#"))
(define-key key-translation-map (kbd "S-£") (kbd "#"))
My solution (note escape sequence):
;; Even though we may have set the Mac OS X Terminal's Alt key as the emacs Meta key ...
;; ... we want to be able to insert a '#' using Alt-3 in emacs as we would in other programs
(fset 'insertPound "#")
(define-key global-map "\M-3" 'insertPound)
As S.Lott said, it's S-3 to insert a number sign (or hash, pound, octothrope).
Why do you want to use the meta modifier to insert it? Also, what is M-3 bound to on your setup? You can get it by doing an C-h-k and then hitting the key combination.
Assuming you are referring to Alt properly and that it's setting the Meta modification bit you can shove
(global-unset-key (kbd "M-3"))
into your .emacs and eval it to disable this from happening.
All "normal" keys are bound to self-insert-command. The shift modifier simply upcases the 'key' which is used to call this function so you get a # instead of 3 when you do a S-3.
Also, I still don't understand why you're using Alt rather than shift to display the # symbol. What do you do when you want to type a #?
I'm running Mac OS X and GNU Emacs 22.3.1. I use a swedish keyboard. I am unable to type braces { }, [ ] in emacs. When trying to type braces I get parenthesis. Since I'm quite new to Mac and emacs I need a little help on configuring emacs to get this right.
(setq mac-option-modifier nil
mac-command-modifier 'meta
x-select-enable-clipboard t)
This is what I use for my swedish keyboard. It even works with svorak A5, if you use it :)
You could also try:
(setq mac-option-key-is-meta t)
(setq mac-right-option-modifier nil)
I'm assuming that you're using a graphical emacs, and not just using the OS X bundled version from within Terminal.
To ensure that Emacs responds to keystrokes in the same way as other OS X apps, try the following:
(setq default-input-method "MacOSX")
And in particular, if you want to use the Option key to enter extended characters not on your keyboard (e.g. "Option-c c" => "ç"), use these settings:
(setq mac-command-modifier 'meta)
(setq mac-option-modifier 'none)
(Put these commands in your ~/.emacs or ~/.emacs.d/init.el emacs startup file, and restart Emacs, or just "M-x eval-buffer" while editing the file.)
(setq default-input-method "MacOSX")
(setq mac-command-modifier 'meta
mac-option-modifier nil
mac-allow-anti-aliasing t
mac-command-key-is-meta t)
Try this. You will be able to use the Alt key as a AltGR and for all the old M-x functions you will have to use your command key.
Bind the relevant keyboard shortcuts to anonymous functions that insert those characters, for example add these lines to ~/.emacs for European Portuguese:
(global-set-key "\M-(" (lambda () (interactive) (insert "{")))
(global-set-key "\M-)" (lambda () (interactive) (insert "}")))
(global-set-key "\M-8" (lambda () (interactive) (insert "[")))
(global-set-key "\M-9" (lambda () (interactive) (insert "]")))
Then save ~/.emacs with C-x C-s and reload it with M-x load-file and type ~/.emacs.
One downside is that this does not work in the mini-buffer, and typing "Alt-9" will insert text in the buffer and not the mini-buffer.
Comparison with other solutions: This solution maintains compatibility with other shortcuts using M-. The solutions by #monotux, #sanityinc, and Abdul Bijur V A do work, but they do not maintain that compatibility, e.g. Cmd-Q no longer quits the program and M-x no longer calls the mini-buffer to execute commands.
The solution by #patrikha doesn't suit touch-typing, which requires the same modifier commands on the right and the left side of the keyboard (Command, Alt/Option, Shift, and Control). For example, with this solution doing M-x requires the left thumb on the left Alt key and the left index finger on the S key, instead of the right thumb on the right Alt key. You could (setq mac-left-option-modifier nil), but that might require a change in habits for letters on the right side of the keyboard.
Notes: If you use AquaMacs, the wiki has a work-around in the section "Inputting {}[] etc. on non-English keyboards, or other keys with the Option modifier".
I also add this line to the end of ./emacs to show the matching of brackets and braces: (show-paren-mode).
I would try a Cocoa based emacs ie version 23. For a mac integrated emacs I would try Aquamacs
I had the same issue with a french keyboard. It looks like an Aquamacs issue (Carbon Emacs does not replace { with ()).
The change in emacs above work fine and I could type brackets but I could not use standard shortcuts anymore (Ctrl+C/Ctrl+V for instance).
Aquamacs provides a workaround.
Menu Bar > Options > Option, Command, Meta keys > select ...Meta & French
It worked fine for me. However it may not work for swedish, no swedish keyboard option.
Using Aquamacs:
From the main menu, go to Options - Option, command, meta keys and select "option for composed characters".
The braces and the brackets work as with the standard Mac keyboard.
You don't need to remember those programming like things: Here is the answer. Go to Keyboard preferences, and check the "Show keyboard and character viewer in menu bar". After that, check on the menu bar near the battery meter for the icon and start double clicking any character you want.
Background information:
I'm on a Mac, and I've just upgraded to Emacs 23.1 via http://emacsformacosx.com/. There are a few issues, notably the lack of full screen ability.
I've attempted to get around this last issue by installing Megazoomer, which adds a global input manager bound to Cmd-return. This causes the currently forward application to maximise. However, Emacs reports that <s-return> is undefined. I've never seen an s-[key] mentioned before, and Google isn't forthcoming with an answer.
So, two parts:
What does s-[key] mean? This is purely for my satisfaction; and
Can I tell Emacs to ignore this key combination and let the key combination carry through to the system (so that hopefully I can have full screen Emacs back again)?
EDIT: so 1) is resolved, and as to 2) I've got: (global-set-key (kbd "<s-return>") 'ignore), which at least stops the error. However, Emacs still swallows the key combination, which isn't ideal.
It's the Super key, like M- is the Meta key (alt key on a PC keyboard, Command key on your keyboard) and C- is the Control key.
I have of course never actually seen a super key on my keyboard... they are from a long gone era. Wikipedia has an image of this impressive "Space Cadet keyboard" which has all the modifiers you'll ever need:
With plain Emacs 23.1 on a Macbook Pro, I can map the right option key to super by
(setq ns-right-option-modifier 'super)
Your other choice seems to be the function key, which would be ns-function-modifier. However, fn might have other uses, whereas Emacs’ default is to map ns-right-option-modifier to ’left (ie, the same effect as the left option key, which I at any rate need to get the # character!), so the right option key is to some extent redundant.
Left-handers may want to reverse this.
For the question about what the s-[key] means, on ubuntu box it means the Windows® shaped key. What it means on the OSX systems, I do not know.
As for maximizing windows, could you try this?
(It should work, iif OSX runs an X server somewhere underneath it all)
(if (equal (window-system) 'x)
(progn
(defun toggle-fullscreen ()
"Toggles fullscreen"
(interactive)
(x-send-client-message nil 0 nil "_NET_WM_STATE" 32
'(2 "_NET_WM_STATE_MAXIMIZED_VERT" 0))
(x-send-client-message nil 0 nil "_NET_WM_STATE" 32
'(2 "_NET_WM_STATE_MAXIMIZED_HORZ" 0)))
(global-set-key (kbd "C-c C-y") 'x-clipboard-yank)
(global-set-key (kbd "M-RET") 'toggle-fullscreen)))
This little snippet is what I use to toggle fullscreen on my *nix computers. And yanking from X's clipboard is a neat ability to have.
As for how to set keybindings, use global-set-key for mode independent keybindings.
(Add it to your .emacs file if you want it to be permanent.)
(setq ns-command-modifier nil)
That is supposed to do what you want. However, it's having somewhat unpredictable behaviour on machine when I test it, so be warned.
