When I turn on icicles mode in emacs, it kinda mess up delete-selection-mode.
After copied some text, if I try to yank it into a highlighted region, instead of replace that region, it will append at the end of the region. I say kinda because, I could still use backspace or directly type text to replace the highlighted region. Only yanking behavior is not right.
Is there some option in icicles mode to fix this yank behavior? So far I haven't found any.
Thank you
M-x icicle-send-bug-report RET
Yes, M-x icicle-send-bug-report RET
Give a complete recipe, starting from emacs -Q. It sounds like you have some other setting somewhere that is interfering. I use Icicles with delete-selection-mode all the time.

Something in my config is unsetting/overwriting some standard keybindings for C-c C-e so that commands in various major modes don't work properly. In AUCTeX C-c C-e should start the "insert environment" dialogue and in org-mode the same keys should start the export/publish dialogue, but in both of these modes C-c C-e is undefined and emacs just waits for more input.
I know I could start emacs with -Q and load packages until something breaks (and if I load emacs that way and open a file in org-mode, the keybindings work as they should) but, like lots of people, at some point my init file became monstrously big. Is there a quicker, smarter way?
[EDIT] Nothing in my config is unsetting C-c C-e explicitly.
The debugger might give you enough clues to sort it out. Try adding the following to the beginning of your .emacs:
(debug-on-entry 'global-unset-key)
You might need to try 'local-unset-key as well. For details see the debugger manual.
Binary search is your friend.
Go to the middle of your .emacs and add (error "here"), then launch Emacs and see if the problem persists.
If it does, then insert another error line half way between the current and the top of the file, if not, comment out the current error and add one half way between the current and the bottom.
Repeat the bisection process until you isolate the line or two which are responsible for causing the problem.
You could use C-h k C-c C-e to find out which function is bound to your combination.
In the popped up help buffer, you will get the function name, its documentation and a link to the file where it is defined. Follow that link and you will end up at the place of the function definition.
At this point, it should be simple to identify which package that is responsible for redefinition of your keybinding using the name of the file.
If this does not help, you could M-x rgrep in your customization directory for 'C-c C-e' or 'C-e' and manually check everything.
I've been Googling around and looking at Emacs built-in help but I have yet to determine how to scroll up (or down) in Emacs ansi-term.
I'm using Emacs 23.3.1, OS X, in iTerm2. Thanks!
Edit: I've noticed most the advice people give me doesn't work in ansi-term but does work in eshell. I have since moved to eshell.
In general, if you don't need full screen terminal emulation, shell or eshell are better choices.
However, if you decide to stick with ansi-term, press C-c C-j to go into line mode. Then you can move around normally with the usual cursor movement keys. Press C-c C-k to get back into char mode to interact with the terminal.
Alternatively, you can scroll backwards a screen at a time with C-c C-v and just enter text to scroll back to the terminal input point.
Take a look at the Emacs documentation on term-mode (most of which applies equally to ansi-term) for more information.
Shift-page up/down (in Emacs-speak, S-prior/S-next) will work using the default bindings.
(While the normal C-h m/C-h b don't work to see mode information and bindings in this mode, you can still use C-c M-x describe-mode/describe-bindings, or depending on your setup, use F1 or the help key instead of C-h.)
install evil-mode at first, press C-z to switch to vim key binding.
You can use C-f, C-b to scroll up and down
you can use 20% to jump to to the top 20% of the buffer
you can use /, ?, #, * to search the text in the buffer.
all the grep/filter commands now usable (occur, swiper, helm-swoop, .... just name a few)
you can narrow/widen the buffer
you can yank text
Have you tried: Page up, up arrow, Ctrl-V,Alt-V
For ansi-term, I have this in my .emacs:
(add-hook 'term-mode-hook
(function
(lambda ()
(define-key term-raw-map [?\C-c prior] 'scroll-down)
(define-key term-raw-map [?\C-c next] 'scroll-up))))
Then I can use C-c pgup and C-c pgdn to scroll.
I was having the same issue but with multi-term (zsh), and after reading the response from #muffinista (the C-v did not work for me) but the Alt-v worked to go 1 page, after that you can use the normal C-p and C-n to scroll up and down.
This worked for me, but it depends a lot on which term you are using and key bindings you might have.
Up and down are Ctrl-P and Ctrl-V. There's a whole long list here
I reciently switched to emacs starter kit which includes the ido package.
ido has a nice feature that suggests paths when find-file which is usually very handy except when trying to create a new file. When the new file name matches a suggestion in another path ido automatically switches to that path assuming that's what I wanted, but usually its not and I find it annoying.
To workaround the issue I either touch newfile from shell, create a new buffer and save as, or M-x find-file to get the original behavior. I could of course rebind C-x C-f to find-file again but must of the time I like ido-find-file, I just want it to stop automatically switching paths when I type the path explicitly.
I figure there is probably some simple key I can press during ido-find-file to tell it that the file I'm looking for does not exist and to stop making suggestions, or some var I can set to get more desirable behavior?
Try:
C-x C-f C-f
It should kick you out of ido mode into "normal" find file mode
C-j is the key combination you are seeking.
As mentioned: being fast, using C-j to confirm immediately, and using and additional C-f to temporarily switch to the traditional mode are all useful.
Also, when ido has already selected an alternate file path, you can hit C-z to return where you were and temporarily disable that behavior.
A solution for a related problem - ido not asking overwrite confirmation.

On Fido, M-j does the trick.
It's bound to icomplete-fido-exit by default.
I use the emacs command 'highlight-compare-buffers' to see the changes between two files. But I don't know how to turn the highlighting off. It seems like it should be really easy, but I can't seem to figure out how even with lots of googling and searching the emacs help files.
Try:
C-u -1 M-x highlight-compare-buffers
global-highlight-changes is an
interactive autoloaded Lisp function
in `hilit-chg'.
(global-highlight-changes &optional
arg)
Turn on or off global Highlight
Changes mode.
When called interactively:
if no prefix, toggle global Highlight Changes mode on or off
if called with a positive prefix (or just C-u) turn it on in active mode
if called with a zero prefix turn it on in passive mode
if called with a negative prefix turn it off
I don't have emacs installed on this box, so this is untested, but highlight-changes-toggle-visibility might work.
Notepad++ has a convenient feature: if you select a word in your text (not necessarily a keyword), the word is highlighted throughout the text. Can this be done in Emacs as well? And if so, how?
It doesn't necessarily have to work exactly like Notepad++ (i.e., via selection); ideally, I would like to set up a key binding that causes all occurrences of the word under cursor to be highlighted.
It would be great if the highlights were permanent, i.e., moving point away from a highlighted word should not cause the highlight to be removed.
Also, it would be useful if there was a solution that made it possible to navigate between highlights (using custom key bindings).
The hi-lock suggestions are good. I think it's easier to use the M-x versions, though:
M-x highlight-regexp RET <REGEXP>
M-x highlight-phrase RET <REGEXP>
highlight-phrase is just a bit of sugar around highlight-regexp that ignores case and translates a space in the regex to match arbitrary whitespace. Handy.
Maybe highlight-symbol.el at http://nschum.de/src/emacs/highlight-symbol/ is what you are looking for:
Type C-s, then type the current word or type C-w. As a bonus, you can now hit C-s again to search for the word.
This is called incremental search.
What I use is idle-highlight
http://www.emacswiki.org/emacs/IdleHighlight
M-x idle-highlight sets an idle timer that highlights all occurences in the buffer of the word under the point.
To enable it for all programming modes, in ~/.emacs.d/init.el:
;; highlight words
(add-hook 'prog-mode-hook (lambda () (idle-highlight-mode t)))
Light-symbol will highlight whatever symbol point is over.
Alternately, you can use occur, which lists all lines matching a regexp. It's useful to quickly see all functions in a class.
Nobody mentioned symbol-overlay mode. It's basically a better rewrite of highlight-symbol-mode. "Better" as in, lacks bugs of original highlight-symbol (such as, temporary highlight getting stuck, or the temporary highlight disappearing for moving inside the highlighted word; or not being able to highlight symbols like *), better integrated, and maintained. See "Advantages" paragraph of its README.
You can install it as usual, with M-xpackage-install (make sure to update package list beforehand with package-list-packages). For reference, at the bottom I attached code I use to enable the mode and disable a few of the more advanced features which you may or may not want.
Notepad++ has a convenient feature: if you select a word in your text (not necessarily a keyword), the word is highlighted throughout the text. Can this be done in Emacs as well? And if so, how?
Once you enable overlay-symbol, occurrences on the screen will be shown for every word that you put cursor upon after a timeout (timeout by default is 0.5s, can be configured with symbol-overlay-idle-time variable). If a word don't get highlighted, this means there's just one match on the screen (the one you put cursor upon), hence there's no need to highlight it.
It would be great if the highlights were permanent, i.e., moving point away from a highlighted word should not cause the highlight to be removed.
To highlight the word under cursor permanently there's a function symbol-overlay-put. To unhighlight call it once again.
In my config example it's bound to Logo+` key.
(require 'symbol-overlay)
(defun enable-symbol-overlay-mode ()
(unless (or (minibufferp)
(derived-mode-p 'magit-mode)
(derived-mode-p 'xref--xref-buffer-mode))
(symbol-overlay-mode t)))
(define-global-minor-mode global-symbol-overlay-mode ;; name of the new global mode
symbol-overlay-mode ;; name of the minor mode
enable-symbol-overlay-mode)
(global-symbol-overlay-mode) ;; enable it
(global-set-key (kbd "s-`") 'symbol-overlay-put)
(setq symbol-overlay-ignore-functions nil) ;; don't ignore keywords in various languages
(setq symbol-overlay-map (make-sparse-keymap)) ;; disable special cmds on overlays
This may not be as nice as what you were hoping but if you put
(global-hi-lock-mode 1)
in your .emacs file then you can type C-x w h REGEX <RET> <RET> to highlight all occurances of REGEX, and C-x w r REGEX <RET> to unhighlight them again. Again, not as elegant as you'd probably like, but it'll work.
Try http://www.emacswiki.org/emacs/msearch.el
All occurences of the text selected with the cursor are highlighted.
You have to drag over the string which you want to highlight. That enables you to easily change the selection without changing the highlight.
If you want to preserve the highlighting of a string you can freeze it.
You can enslave a buffer to another buffer. Text selected in the master buffer will also be highlighted in the slave buffer. That is useful for comparing buffers.
It is also useful for taking notes in one buffer while you investigate the text in another one. You can have a collection of keywords in the notes buffer. Drag over such a keyword and its occurences in the investigated text will be highlighted.
I am using this stuff for years now. I added the freezing quite recently. So, maybe something is broken. If this is the case leave me a note on http://www.emacswiki.org/emacs/msearch or here.
Check Interactive Highlighting
Should be:
C-x w h word <RET> <RET>
Try iedit. It highlights the word at point and lets you edit all occurrences of it easily. With an additional keystroke (C-'), it hides all the lines without that word in it. Very handy!
Commands in library highlight.el
let you (un)highlight text matching a regexp (in this case a symbol), using overlays or text properties. You can cycle among the occurrences. Highlighting can be temporary or persistent. (more info).
This maybe won't highlight but will search for a word without you needing to type it...
when you've reached the word you wanted to search, C-S, then read the full word with C-W then you can C-S and it will search for it. In my Emacs it also highlights all instances in the document.
This package available in Melpa works, you can customize the highlight style as well.
