I need to check if Shift key is pressed.
More exactly I would like to set dired switches depending on whether Shift is pressed.
(defadvice find-file-noselect (around find-file-noselect-set-switches activate)
(let ((switches dired-listing-switches))
;; check if shift is pressed and set or not an "R" switch
(setq dired-listing-switches "-lhRA")
ad-do-it
(setq dired-listing-switches switches)))
Of course, I can have different shortcuts for different dired switches, but I would like to change my switches dynamically during choosing a directory for dired.
Duplicate question (ignoring the 'Windows' part of the other one).
Can I send a keypress to Windows from Emacs?
The best you can do (is as you mention) have different shortcuts. They can be differentiated by capitalization... for example
(global-set-key (kbd "C-x C-D") 'dired-with-some-switches)
(global-set-key (kbd "C-x C-d") 'dired-with-other-switches)

The issue:
I have started a Common Lisp session with a *slime-repl sbcl* in its default vertical split.
I am on a symbol, let's say cond, and press the key for slime-describe-symbol which in my case is ,hh as I am using spacemacs.
This opens a buffer *slime-description* on top of the repl window.
I am now left in a situation where I have to:
move to the split on the right
switch buffer to the slime *slime-repl sbcl*
return to my original buffer
I have to do this every time I open a help file which seems strange as the designed workflow. I would expect this to be possible using a single keystroke.
What is the intended way of managing this?
In plain emacs the keyboard shortcut for moving to the other window is 'C-x o' (other window). I'd assume the easiest way to achieve the automatic cursor movement when describing a symbol would be to define your own custom elisp function by modifying slime-describe-symbol to move the cursor to the slime-description window and (re)bind the keyboard shortcut.
On my machine:
(defun my-slime-describe-symbol (symbol-name)
"Describe the symbol at point."
(interactive (list (slime-read-symbol-name "Describe symbol: ")))
(when (not symbol-name)
(error "No symbol given"))
(slime-eval-describe `(swank:describe-symbol ,symbol-name))
(switch-to-buffer-other-window "*slime-description*"))
and then define the keyboard shortcut to your liking:
(define-key slime-mode-map (kbd "C-c C-d d") 'my-slime-describe-symbol)
(define-key slime-mode-map (kbd "C-c C-d C-d") 'my-slime-describe-symbol)
I have this little problem, I have some key bindings like so C-. C-x or C-. C-m. After I activate the flyspell-mode, I cannot use these commands. In my .emacs file I have the next 2 lines before
(global-unset-key (kbd "C-."))
(define-key (current-global-map) (kbd "C-.") nil)
(global-set-key (kbd "C-. C-l") 'global-linum-mode)
Then, my C-. C-l works, but it does not when the flyspell-mode is activated. The command bound to C-. is flyspell-auto-correct-word. I tried to deactivate it as follows:
;; first try
(defun flyspell-auto-correct-word-disable() (define-key (current-local-map) (kbd "C-.") nil))
(add-hook 'flyspell-mode-hook 'flyspell-auto-correct-word-disable)
;; second try
(define-key (current-global-map) [remap flyspell-auto-correct-word] nil)
None of the tries work, what can I do? I tried in Emacs 23 and 24 and I have the same issue.
What about:
(eval-after-load "flyspell"
'(define-key flyspell-mode-map (kbd "C-.") nil))
Your first solution is almost correct, but you have to remember that the current local map is set up by the major mode, not minor modes. The best option you have it to directly access flyspell-mode-map and modify it (another option would be to find it in minor-mode-map-alist but I think it would be needlessly complicated).
Also, I prefer putting such mode-specific settings within eval-after-load (which means they will be evaluated once) rather than in a hook (in which case the settings are evaluated multiple times: each time one buffer activates flyspell-mode). But this is a matter of preference and either way is fine.
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'.

I'm trying to define the following two keyboard shortcuts to move between windows in Emacs:
C-shift-n: Move to the next window
C-shift-b: Move to the previous window
I thought the following will do it but it doesn't.
(defun select-next-window ()
"Switch to the next window"
(interactive)
(select-window (next-window)))
(defun select-previous-window ()
"Switch to the previous window"
(interactive)
(select-window (previous-window)))
(global-set-key (kbd "C-<S-n>") 'select-next-window)
(global-set-key (kbd "C-<S-p>") 'select-previous-window)
The problem seems to be with the last two lines that define the actual keyboard shortcuts to the functions that switch the windows (if I use simpler keyboard shortcuts instead of Control-Shift-* it works).
So, how do I use kbd to define Control-Shift-n and Control-Shift-p?
Assuming you never use caps lock, here's a super simple solution:
(global-set-key (kbd "C-N") 'select-next-window)
or
(global-set-key (kbd "C-<S-N>") 'select-next-window)
The problem is that when you hit shift you're sending capital N.
I have two problems which are somewhat related I believe:
1) In IDO I'd like to change ido-restrict-to-matches to samething else than C-SPC or C-#. Unfortunately I do not know how to tell emacs that I want a different shortcut (say C-0).
2) I'd like to protect my C-; but whenever flyspell-mode is running it overtakes C-;. My definition is in .emacs as:
(global-set-key (kbd "C-;") 'mark-paragraph)
but apparently flyspell overwrites this... (although even then, if I look in the help M-h k C-; it does say mark-paragraph)
Could somebody please tell me how to bind/unbind keys in these conditions? It has to work without modifying ido.el and flyspell.el and re-building, right?
Thanks very much!
Flyspell provides a customization for the C-; binding, so you can either M-x customize RET flyspell-auto-correct-binding RET or put something like this in your ~/.emacs:
(setq flyspell-auto-correct-binding (kbd "C-~")) ; or a binding of your choice
As for ido, your question is slightly confusing, because it implies there are times when you're using ido outside the minibuffer...
The documentation in ido.el contains the following advice:
;; To modify the keybindings, use the ido-setup-hook. For example:
;;(add-hook 'ido-setup-hook 'ido-my-keys)
;;
;;(defun ido-my-keys ()
;; "Add my keybindings for ido."
;; (define-key ido-completion-map " " 'ido-next-match)
;; )
Using that knowledge, you can change the key bindings like this in your own "ido-my-keys" function:
(define-key ido-completion-map (kbd "C-SPC") nil)
(define-key ido-completion-map (kbd "C-#") nil)
(define-key ido-completion-map (kbd "C-0") 'ido-restrict-to-matches)
There's an additional ido hook specifically for the minibuffer, too, but it's not clear why you would need that: ido-minibuffer-setup-hook.
