I set Alt as the windmove key to switch between frames in Emacs under Mac.
(windmove-default-keybindings 'meta)
This works fine for the GUI version Emacs (the one with the widgets and other windows decorations), but not if I start emacs with emacs -nw from a Mac Terminal.app. For example, if I split window first with C-x 2, and press Alt + <Down>, then Emacs reports
ESC + <Down> is undefined.
Can anyone help?
Emacs version is 24.4 installed from brew install.
It seems the easiest way is to just install iterm2. And in the Preferences > Profiles tab. Select your profile on the left, and then open the Keyd tab and set the option key to +ESC.
Then in your emacs setup set the key manually,
(global-set-key (kbd "ESC <up>") 'windmove-up)
(global-set-key (kbd "ESC <down>") 'windmove-down)
(global-set-key (kbd "ESC <right>") 'windmove-right)
(global-set-key (kbd "ESC <left>") 'windmove-left)
I suggest you to use iterm2 since it's a better terminal. But in case you want to use terminal.app don't forget to check the Use option as meta key in Preferences > Settings > Keyboard, it works to some extend with the default emacs.
The same issue is true for Ubuntu when I use terminator as a terminal.
You can work around this problem by using the win-switch package which works fine in every case for me. Here you have a simple configuration that you can put in your init file (.e.g.: .emacs):
;; install win-switch package using package manager
(if (package-installed-p 'win-switch)
nil
(package-install 'win-switch))
;; my favourite quick keybindings
(global-set-key (kbd "M-<left>") 'windmove-left)
(global-set-key (kbd "M-<right>") 'windmove-right)
(global-set-key (kbd "M-<up>") 'windmove-up)
(global-set-key (kbd "M-<down>") 'windmove-down)
The win-switch package has many other powerful utilities which are further detailed in the commentary part of the code.

I'm trying using Emacs and tmux in the Terminal.app, and having difficulty getting the mouse to work correctly.
If I use Emacs outside of tmux, then I can use the mouse to click on text to jump around the buffer.
However, if I am inside tmux, and I start editing a file in Emacs, then I can't click around. I have to do
M-x load-file ~/.emacs.d/init.el
.. to get it working.
Here is the content of my init.el
(require 'package) ;; You might already have this line
(when (< emacs-major-version 24)
;; For important compatibility libraries like cl-lib
(add-to-list 'package-archives '("gnu" . "http://stable.gnu.org/packages/")
'("melpa" . "http://melpa.org/packages/")))
(package-initialize) ;; You might already have this line
;; magit
(global-set-key (kbd "C-x g") 'magit-status)
(global-set-key (kbd "C-x M-g") 'magit-dispatch-popup)
(global-set-key (kbd "C-c SPC") 'ace-jump-mode)
;; mouse
;; enable mouse reporting for terminal emulators
(unless window-system
(xterm-mouse-mode 1)
(global-set-key [mouse-4] (lambda ()
(interactive)
(scroll-down 1)))
(global-set-key [mouse-5] (lambda ()
(interactive)
(scroll-up 1))))
..and my tmux.conf
set -g mouse on
bind X confirm-before kill-session
bind C-s set-window-option synchronize-panes
bind r source-file ~/.tmux.conf \; display "Reloaded!"
set -g window-active-style 'fg=colour250,bg=black'
bind -t emacs-copy C-WheelUpPane halfpage-up
bind -t emacs-copy C-WheelDownPane halfpage-down
# plugins
set -g #plugin 'nhdaly/tmux-scroll-copy-mode'
run '~/.tmux/plugins/tpm/tpm'
Versions
tmux version 2.1

I am using logitech pc keyboard with my eMac and want to use Home and End buttons as usual. I've already rebound them for mac terminal. And want to rebind them in emacs as well.
Like this:
(global-set-key [home] 'move-beginning-of-line)
(global-set-key [end] 'move-end-of-line)
As for Terminal.app, its default key bindings grab Home and End for itself (to scroll to the beginning and end of the terminal output), and lets Shift-Home and Shift-End through to the application. You can switch this around in under "Settings" -> "Keyboard" in the Terminal preferences.
In your .emacs file put something like this:
(add-hook 'after-init-hook
'(lambda ()
(define-key global-map [C-home] 'beginning-of-buffer)
(define-key global-map [C-end] 'end-of-buffer)
(define-key global-map [home] 'beginning-of-line)
(define-key global-map [end] 'end-of-line)
;;; much more semi private stuff deleted
))
It works for me since ancient times.
If I runs emacs in a terminal (i.e start emacs in iTerm2 with emacs -nw)
using windmove and it's default bindings, I should be able to navigate between windows using various combinations of Shift + → ← ↑ ↓, Also paredit has bindings that involve Ctrl/Meta + → ← ↑ ↓, these all work fine in (say) an elisp mode buffer.
Looks like the arrow keys functionality relies on emacs decoding terminal escape sequences, via (I think) the input-decode-map
However, if I set the major mode as clojure-mode then the decoding of the escape sequences appears to be disabled (or overwritten). When I execute those bindings I just get the escape sequence instead.
What's going on with the bindings in clojure-mode ?
Versions:
emacs 24.3.1 (have tried maxosxforemacs.com version and homebrew)
clojure-mode 20131117.2306 (have tried other versions)
OSX 10.8.5
iTerm2 1.0.0.20131124
(disclaimer: I raised this as an issue on clojure-mode, but no solution is forthcoming)
UPDATE 2013/12/10: To be absolutely clear: this problem is specific to clojure-mode. emacs -nw in iTerm + arrow keys works fine in other major modes. I'm sure I'm doing something silly that is causing this, I'd like to know what.
Almost identical setup here, but no similar problem. Here's what I would do anyway. First, evaluate the following emacs-lisp code in the scratch buffer.
(progn
(define-key input-decode-map "\e[1;2D" [S-left])
(define-key input-decode-map (kbd "M-[ 1 ; 2 C") [S-right])
(define-key input-decode-map (kbd "M-[ 1 ; 2 B")[S-down])
(define-key input-decode-map "\e[1;2A" [S-up])
(define-key input-decode-map "\e[1;6A" [S-C-up])
(define-key input-decode-map "\e[1;6B" [S-C-down]))
Try the windmove bindings when clojure-mode is activated. If this fixes your problem, and assuming your TERM environment variable is set to xterm-256color, put the following in your init.el
(if (equal "xterm-256color" (tty-type))
(progn
(define-key input-decode-map "\e[1;2D" [S-left])
(define-key input-decode-map (kbd "M-[ 1 ; 2 C") [S-right])
(define-key input-decode-map (kbd "M-[ 1 ; 2 B")[S-down])
(define-key input-decode-map "\e[1;2A" [S-up])
(define-key input-decode-map "\e[1;6A" [S-C-up])
(define-key input-decode-map "\e[1;6B" [S-C-down])))
Hope this helps.
Check your settings in Iterm, more specifically the "Global shortcut keys". Those will take precedence over what is sent to emacs. C-Shift-Arrow is used to switch tabs in Iterm I believe and may be interfering with emacs.
I'm using Emacs in Mac OS X terminal, installed with homebrew.
My CTRL key is my C key, and the ALT key is Meta.
How would I define key-bindings for CMD key combinations?
For instance, I want to set CMD-(right arrow) to go to the end of the line.
EDIT
I've tried #nickcarlo's suggestions below
(setq mac-command-modifier 'super)
(global-set-key (kbd "s-<right>") 'move-end-of-line)
I don't think CMD key is being set to super properly, since I don't see s-foo in the mini-buffer as I would if I had typed C-x or M-x or anything. I noticed that CMD-right, when I have two terminal windows open, switches between the two terminal windows, so I thought that might be blocking any custom setting. However, I tried:
(global-set-key (kbd "s-9") 'move-end-of-line)
.. and CMD-9 still does nothing, except beep to tell me I've pressed something wrong.
Setting non-CMD key-combos seems to work fine, like:
(global-set-key (kbd "C-w") 'move-end-of-line)
You can set it with something like:
(global-set-key (kbd "s-<right>") 'move-end-of-line)
"s" being the reference to your command key.
PS: I'm not on my mac right now so I'm not sure what exactly you need to write to set it to the specific keys you mentioned to move it to the end of line but command is represented by an s in emacs.
EDIT
Just tested this on my mac. This is the exact code you'd write (if you wanted to set it globally) to bind your command key + right arrow key to move your cursor to the end of line.
If the above doesn't work, you could also try
(global-set-key (kbd "\s <right>") 'move-end-of-line)
The difference between the one above and this one is that the above equates to CMD+right and this one equates to CMD and then release CMD and hit the right key. Both work on OS X on my system.
Also check out the following post to set your CMD as the super key in case your Emacs doesn't already register it as such:
http://ergoemacs.org/emacs/emacs_hyper_super_keys.html
Specifically, you can use the following code to set up your CMD key as Super:
(setq mac-command-modifier 'super)
In Aquamacs, what worked for me is the following
(global-set-key (kbd "A-r") 'my-command)
Step 1: c-x c-f .emacs // opens .emacs file
Step 2: Add the following lines at the end of .emacs file
;; changing the command to control
(setq mac-command-modifier 'control)
Step 3: Save .emacs file
Step 4: M-x eval-buffer //M-x = Alt-x // This evaluates .emacs buffer and reloads Emacs
Step 5: Try CMD-e to go to end of the line. // Now CMD acts like control
Step 6: Still CMD-e does't work restart Emacs.
Enjoy Using Emacs!
I have configured my emacs to run zsh shell within ansi-term. However, copy/paste no longer works i.e. nothing is getting pasted from kill-ring to the terminal.
Changing the TERM to vt100, or eterm doesn't solve the problem.
Would appreciate any ideas or solution.
To provide context I have configured ansi-term as follows:
(global-set-key "\C-x\C-a" '(lambda ()(interactive)(ansi-term "/bin/zsh")))
(global-set-key "\C-x\ a" '(lambda ()(interactive)(ansi-term "/bin/zsh")))
You may want to simply switch between character mode and line mode while using the terminal. C-c C-j will run term-line-mode, which treats the terminal buffer more like a normal text-buffer in which you can move the cursor and yank text. You can switch back to character mode by running term-char-mode with C-c C-k.
As described in this lovely blog snippet, there's a function, term-paste, in term.el, that does exactly what you want. By default it's bound only to S-insert but the blog's recommended C-c C-y seems like a good suggestion.
ansi-term, in char-mode, takes the ordinary bindings for the terminal emulation. You need a new binding, plus a way to output to ansi-term correctly. I use this:
(defun ash-term-hooks ()
;; dabbrev-expand in term
(define-key term-raw-escape-map "/"
(lambda ()
(interactive)
(let ((beg (point)))
(dabbrev-expand nil)
(kill-region beg (point)))
(term-send-raw-string (substring-no-properties (current-kill 0)))))
;; yank in term (bound to C-c C-y)
(define-key term-raw-escape-map "\C-y"
(lambda ()
(interactive)
(term-send-raw-string (current-kill 0)))))
(add-hook 'term-mode-hook 'ash-term-hooks)
When you do this, C-c C-y will yank. It only does one yank, though, and you can't cycle through your kill-buffer. It's possible to do this, but I haven't implemented it yet.
The above solutions work well for copying text from some buffer to ansi-term, but they aren't able to copy text from ansi-term to another buffer (eg copy a command you just ran to a shell script you're editing). Adding this to my .emacs file solved that problem for me (in Emacs 24.4):
(defun my-term-mode-hook ()
(define-key term-raw-map (kbd "C-y") 'term-paste)
(define-key term-raw-map (kbd "C-k")
(lambda ()
(interactive)
(term-send-raw-string "\C-k")
(kill-line))))
(add-hook 'term-mode-hook 'my-term-mode-hook)
Note that if you want to bind kill/yank to a keystroke that starts with the ansi-term escape characters (by default C-c and C-x), and want this to work in the unlikely event that those change, you can instead define your keystrokes (without the leading escape) to term-raw-escape-map, as is done in user347585's answer.
These other solutions don't work well for me, switching between character mode and line mode causes ansi-term to stop working properly randomly, and setting ansi-term's term-paste to C-c C-y (based on Glyph's link), didn't work the code snippet was for term, not ansi-term:
(eval-after-load "ansi-term"
'(define-key ansi-term-raw-map (kbd "C-c C-y") 'term-paste))
I enabled xterm-mouse-mode, after that I was able to select text using mouse and copy using standard Mac command C button in ansi-term in emacs GUI in Mac OS X,
