When I add a label in emacs to a .tex file, I used to reload the file to get it to show up in RefTeX. i.e. C-c ) wouldn't have the new label unless I reloaded the file.
After some searching I found that C-u C-c ) will refresh RefTeX before trying to do the reference. This works as I would like, but I would like to use C-c r for this command instead of typing C-u C-c ) every time. How do I do this?
Thanks,
Jim
I don't use reftex but as far as I can understand you want just to define a binding:
(define-key reftex-mode-map (kbd "C-c r") 'reftex-reference)
Building on Oleg's answer:
Maybe it would be better to feed it the C-u argument already if that's what you are after:
(defun call-reftex-reference-directly ()
(interactive)
(let ((current-prefix-arg 4)) ;; emulate C-u
(call-interactively 'reftex-reference) ;; invoke reftex-reference
)
)
(define-key reftex-mode-map (kbd "C-c r") 'call-reftex-reference-directly)
Maybe try if this works for you?
You can type r in the label selection buffer to refresh it without reloading the file. The refresh is instantaneous (unless you have very large/very many linked files).

I simply want to clear the repl buffer so that a single prompt eg (user>) is left on the first line.
I have a keybinding:
(put 'erase-buffer 'disabled nil)
(global-set-key (kbd "C-x C-<backspace>") 'erase-buffer)
But this gives the message :
text is read only
There is the option C-c C-o but this only clears the last return value.
When using python, and run-python the following command C-x M-o which i believe is comint-clear-buffer
cider-repl.el provides a function cider-repl-clear-buffer which by default is bound to:
M-x c-r--bu RET
as C-c M-b is not used by cider-repl as far as I am aware:
(add-hook 'cider-repl-mode-hook
'(lambda () (define-key cider-repl-mode-map (kbd "C-c M-b")
'cider-repl-clear-buffer)))
cider-repl.el also provides cider-repl-handle-shortcut which is bound to ,.
Which will prompt you to many commands, such as clear (which you want), ns (to change namespace), refresh, reload and many others
I find pressing , followd by enter (to choose clear, faster/more convenient than the other answer.)
Note: you need to type , into the repl while the line is empty, it works for both evil and normal emacs keybinds
This is probably simple, but I've been trying it for a couple days now without success. I have a tag called :urgent:, which I can access through:
C-c / m urgent
Question is, how can I create a shortcut to get it done with, say, f9?
(defun hello-world ()
"My doc-string."
(interactive)
(org-tags-view nil "urgent"))
(global-set-key [f9] 'hello-world)
;; or, use the following form instead of the one immediately above:
;; (define-key global-map [f9] 'hello-world)
A related question was asked here. But the answer is to get used to the new way autocomplete works in helm. I cannot get used to it, here's why.
Say, I want to open a file /home/user/work/f.txt. I do C-x C-f, it takes me to current dir, say /current/dir/. I hit Backspace and notice that autocomplete won't let me delete /. Ok, turn off autocomplete with C-Backspace. Then kill the line C-a C-k and start typing. Notice that autocomplete doesn't work, turn it back on C-Backspace. Normally I would type the part that I know is probably unique, e.g. /hom and hit Tab.
Not here. As soon as I type /ho, autocomplete resolves it to /home/, but since I type fast, I end up with /home/m, and continue typing now meaningless characters until I notice it. Chances are, by that time I got autocompleted into directories that I had no intent of going.
So I have to constantly watch what autocomplete is doing, rather than rely on what I type and only checking suggested completions when I hit Tab.
I also find myself descending into wrong directories due to occasional typo, and then having difficulty going up a level -- evil autocomplete won't let you fix the situation with a couple of Backspaces.
This interaction of autocomplete behavior and the removal of Tab functionality completely upsets my work, so much that I decided to ask this question. I am looking to either:
restore the old functionality
learn how to use autocomplete in a meaningful way, or
configure helm's C-x C-f to behave more like a linux command line
Please help.
Here are some ido tricks if you want to start using it.
Let me know if helm is better, perhaps I'll switch over.
I tried once shortly, but didn't like it.
Basic setup:
This will give you `ido-find-file on C-x C-f.
(ido-mode)
(setq ido-enable-flex-matching t)
Smex setup:
Install from https://github.com/nonsequitur/smex.
(require 'smex)
(global-set-key "\C-t" 'smex)
Switch buffers with ido:
(global-set-key
"η"
(lambda()(interactive)
(when (buffer-file-name)
(save-buffer))
(ido-switch-buffer)))
(global-set-key
(kbd "C-η")
(lambda()(interactive)
(let ((ido-default-buffer-method 'other-window))
(ido-switch-buffer))))
Tricks:
;; 1
(add-hook 'dired-mode-hook
(lambda()
(define-key dired-mode-map "j" 'ido-find-file)))
(add-hook
'ido-setup-hook
(lambda()
;; 2
(define-key ido-file-dir-completion-map "~"
(lambda ()(interactive)
(ido-set-current-directory "~/")
(setq ido-exit 'refresh)
(exit-minibuffer)))
;; 3
(define-key ido-buffer-completion-map "η" 'ido-next-match)
;; 4
(define-key ido-buffer-completion-map (kbd "C-p")
'ido-fallback-command)
;; 5
(define-key ido-completion-map (kbd "C-.") 'smex-find-function)
(define-key ido-completion-map (kbd "C-,") 'smex-describe-function)))
Quick open file from dired.
Move to home directory one key faster (i.e. ~ instead of ~/).
Cycle buffer candidates with the same key that shows the candidates (a la C-TAB in Firefox).
Useful to have a fall back when you want to create a file-less buffer (ido will try
select an existing buffer unless you fall back).
Useful to jump to function definition/documentation.
If you want TAB completion of directories and file names, map helm-execute-persistent-action to the TAB key:
(define-key helm-map (kbd "<tab>") 'helm-execute-persistent-action)
See also the answer to "How can I change emacs helm-find-file default action[...]".
I want to map C-f C-b as moving forward and backward by a fixed amount of lines in a file.
I did this:
(global-set-key (kbd "C-f") 'next-line)
(global-set-key (kbd "C-b") 'previous-line)
but I don't know how to specify an argument before the next-line command. I guess I should use digit-argument but I am unable to write the command in a correct way.
You've changed your question to be about how to bind directly to key sequences
This binds C-c l to C-u 5 C-n
(global-set-key (kbd "C-c l") (kbd "C-u 5 C-n"))
One of the possible alternatives would be define a new function:
(defun my-next-line ()
(interactive)
(next-line 5))
(global-set-key (kbd "C-f") 'my-next-line)
Otherwise, if it is just something you can accomplish with the keyboard you might want to use
M-x name-last-kbd-macro
and save it in your .emacs file
M-x insert-kbd-macro
and have emacs implement the function for you.
It will just get the name you gave in your call to name-last-kbd-macro
I'm using gdb-many-windows, which contains five windows to switch between. Is there a shortcut I can use to get to a specific window?
You probably already know that C-x o gets you to the next window. You can extend this to go to any arbitrary window with C-u <windowoffset> C-x o.
So, you can use C-u 2 C-x o to switch to the second window ahead of your current one.
This wraps around the window list (so in your case of 5 windows you could do C-u 4 c-x o to go back one.
You can also use negative numbers as well to go backwards.
Lastly, it takes a bit more setup, but Thomas's suggestion to use WindMove is very useful. It wasn't configured by default for me to any useful key binding. I add the following snippet to my (mac) .emacs file, whch lets me switch windows via control-arrow (you will need to reload .emacs by starting up or via 'M-x load-file')
(global-set-key (kbd "M-[ 5 d") 'windmove-left)
(global-set-key (kbd "M-[ 5 c") 'windmove-right)
(global-set-key (kbd "M-[ 5 a") 'windmove-up)
(global-set-key (kbd "M-[ 5 b") 'windmove-down)
Some people find WindMove more convenient than C-x o. It allows you to navigate between windows using Shift + arrow keys.

Edit: If you decide to use WindowNumberingMode (that's what I use) you might find it useful to pin buffers to windows (so, for instance, Meta-1 switches to the buffer you expect it to switch to, not just the first window). One way of pinning is described in Pin Emacs buffers to windows (for cscope).
Window switching is so important in emacs, I have these settings.(Still feel these are not good enough)..
may help someone else..
(global-set-key "\M-t" 'other-window) ;; was transpose words
(global-set-key (kbd "C-x O") (lambda () (interactive) (other-window -1))) ;; back one
(global-set-key (kbd "C-x C-o") (lambda () (interactive) (other-window 2))) ;; forward t
I use switch-window.el.
You can choose a window by visual way with 'switch-window'.
