Sometimes in a long commit log, it's really painful to navigate the all-expanded diffs.
(You get expanded-diffs when hitting enter from the magit-blame-mode for example)
Is there a way to collapse these diffs?
In any buffer you can type C-hm to see the major and minor mode descriptions, which almost always includes the key bindings defined by each mode (and if it doesn't, you can type C-hb and then search for the mode you're interested in).
Major mode magit-diff-mode includes the following bindings:
M-1 magit-show-level-1-all
M-2 magit-show-level-2-all
M-3 magit-show-level-3-all
M-4 magit-show-level-4-all
M-H magit-show-only-files-all
M-S magit-show-level-4-all
M-g magit-goto-diffstats
M-h magit-show-only-files
M-n magit-goto-next-sibling-section
M-p magit-goto-previous-sibling-section
M-s magit-show-level-4

In Windows 7 / Emacs 24.5
Copy text e.g. "example" in the kill-ring
M-x
C-y (yank)
Success show text "example" in the minibuffer
But if turn on CUA-mode, the text "example" not yank (paste) by 'C-v' in the minibuffer.
CUA mode makes C-v the yank/paste command.
If you start Emacs with :
emacs -Q
Then turn on CUA mode (M-x cua-mode) you'll see that C-v works as you expect.
Without knowing your setup it's difficult to be sure but it's likely you're using a package which modifies the behavior of M-x (E.g. smex, Ido, ivy, etc.)
It's likely CUA mode won't really have anything to do with this problem. You can verify this by trying to do C-y to yank in the minibuffer too.
Packages which enhance M-x may provide a way to allow you to drop out temporarily, so you can yank text in-place.
Update
From your comments we know you are using Helm, which overrides some bindings in the minibuffer, including C-v which is bound to page down.
Because bindings are applied at different mode (context) scopes, the minibuffer modemap (list of key bindings) will override anything that's applied at a more general context (such as cua mode)
To work around this you'd need to add a binding specifically for cua-paste in the affected mode map. It would need to be applied after Helm has loaded.
In the menu-bar of Emacs-23 under [Edit] there is Cut, Copy, Paste which are all explicit clipboard related commands ; the traditional C-w, M-w, C-y are no longer offered, and these no longer have an effect relevant to X.
What is the cleanest way to make the traditional commands clipboard-aware? It seems there must be some more systematic way than just redefining everything. C-h C-n did not help me.
Is it intended to hide the traditional command from users?
Edit: Or at least: a command to "synchronize" with the clipboard.
X has two "clipboards": the primary selection, and the clipboard. Emacs 23 uses the primary selection by default, but it seems you want the clipboard. You can enable this with the following in your .emacs:
(setq x-select-enable-clipboard t)
This setting changed in Emacs 24 to use the clipboard by default. See also: http://emacswiki.org/emacs/CopyAndPaste
I am new to Emacs. I find it is powerful and very convenient IF one can master its set of commands. I also believe anyone can do this with patience, and the eagerness to learn and USE the software. However it will be much nicer for beginners, and seasonal users to have some command helper plugin that do following thing:
When the user start typing any CONTROL or META, COMMAND, or any special keys, a "ajax-like" or "smart search" window appear below or in the minibuffer showing help text like, for example: If I hold "CONTROL", command helper windows shows:
C-p Up one line
C-n Down one line
C-f Forward one character
C-b Backward one character
C-a Beginning of line
C-e End of line
C-x ...
Then if I continue to type "x" while holding "CONTROL", the window will update and show something like:
C-x C-a add-mode-abbrev
C-x C-b list-buffers
C-x C-c save-buffers-kill-emacs
C-x C-d list-directory
C-x C-e eval-last-sexp
C-x C-f find-file
C-x C-h inverse-add-mode-abbrev
C-x TAB indent-rigidly
C-x C-l downcase-region
C-x C-n set-goal-column
C-x C-o delete-blank-lines
I have tried googling it, but it doesn't seem exist yet. So I guess this is more a feature request for EMACS rather then a question. But it is great if somebody can write a plugin/module to do this.
I do not believe this is out there, but I also believe that it is not really needed. It would just clutter the screen, though, maybe for a rookie it might be indeed useful.
For now, you might consider printing a cheatsheet.
Do not lose hope, I learned it without any sort of help, the key is indeed to just use it often.
Also, there is quite a good logic behind it all, so if you read up the structure in a cheatsheet or anywhere else, then it might help you "guess" what is the right key combo sooner than later.
EDIT: I actually myself asked a similar question, at least the same functionality was required. I accepted an answer which apparently mentions that Icicles offers this functionality.
Also, one advise is that after you type the prefix key, e.g. C-c, typing C-h afterwards will show you the possible completions.
This leads me to the following:
I believe we could use code like:
"If last key is a prefix key, run C-h*, switch back to previous buffer and rehit the last prefix key"
*this is a general method, working even for my own poorly designed minor mode
I also don't know an existing package that would do that, but here's a couple of tips.
To get an overview of all available bindings, press C-h b. The displayed buffer looks fairly raw, because it includes all ways used to enter special characters (and they are usually at the top), but you can search it with C-s if you remember at least a part of the command name.
If you know the prefix (e.g. C-x) but don't remember what comes next, you can follow it with C-h instead (type C-x C-h). That will bring up a similar buffer that only contains bindings that start with the same prefix. It's one of the more obscure features, I think.
Speaking of "if I hold Ctrl", though, showing hints when you've just pressed Ctrl and nothing else if currently impossible to implement at the Lisp level. That would require some lower-level changes.
There are too many keybindings in emacs for this to be practically useful.
I agree with the other responses and just wanted to add that I found the built-in tutorial very useful for getting past the basics. You can reach the tutorial with C-h t.
You'll probably end up changing several of the default bindings, but learning them will help you find your way around new modes (assuming that they work in an "emacsy" way).
I come back to this be cause I found a perfect solution and can't live without it: The emacs-helm and which-key
Is there a way I can stop needing C-X before any shortcut and, for example, just use C-c to leave?
Also, if possible, what disadvantages could this have?
I'm looking for a simpler way of using GNU Emacs, but not sure if I can find one.
(this is too long for a comment)
Not really an answer but I know that some people hate the "C-x anything" in Emacs not just because you have to "type a lot of keys" but also because from a touch-typing point of view C-x doesn't make that much sense.
But of course in Emacs everything is configurable. I'm using "C-," instead of C-x and I honestly find it much easier this way.
I use my left pinky to hit CTRL, which is the key physically located at the left of 'a' on a QWERTY keyboard: i.e. the key that used to be CTRL but that now often is labelled CAPS-Lock [and you can remap it to CTRL].
I then touch-type ',' with my right hand.
To this end I added this to my config:
(define-key global-map [(control ,)] ctl-x-map)
You won't have less keys to type to do, say, a C-x C-c (which you can now do both by doing C-x C-c or by doing C-, C-c), but at least you won't be distorting your fingers as much ; )
Also note that as explained here (see user "scottfrazer"'s +40+ upvoted and accepted answer) it may be better to create a minor mode for all your key mappings instead of directly define a global mapping:
Globally override key binding in Emacs
My recommendation is to first learn the standard Emacs key bindings, then, after a while change whichever ones you think will do you the most good to change.
See also CUA mode, in the Emacs docs -- I don't use or recommend CUA mode, but a lot of people (esp. newbies?) use it to keep their cut, copy, paste key habits.
After looking at the source code of boon.el, I found out about ctl-x-map. C-x is a prefix key, prefix keys often have their own maps.
To use M-m for C-x shortcuts and unbind C-x, use this
(global-set-key (kbd "M-m") 'ctl-x-map)
(global-set-key (kbd "C-x") nil)
I think it is a very bad idea, because the C-x prefix can handle such situations like C-x s vs C-x C-s. And: you are really f*cked when you read emacs tutorials and have your own keybindings
If you want some other keybindings read ErgoEmacs Keybinding or How to Set Emacs's User Interface to Modern Conventions
I am using Emacs and most shortcuts work normally, but M-Del for deleting a word backwards produces either an error at the bottom of a `scan' error, and at other times moves the cursor a set of lines below. Any ideas why this may be happening? M-Del works fine for deleting forward words. (** from a comment made below it appear that the command is mapped to a down paragraph lisp function instead of delete a word backwards? How can I reset the mappings to the standard one?)
Best.
writing lisp emacs key binding and cannot specify the <delete> character
has the answer (by Gilles). It looks like there is a bug on some systems due to an overlap with a shell command shadow translating ESC-x to ESC C-d
it can be seen from running
M-x load-library edmacro
M-x edmacro-insert-key M-del
giving ESC C-d
in the folder ~/.emacs.d/ creating a file init.el and inserting
(global-set-key [escape delete] 'backward-kill-word)
this though overrides all uses of ESC from M (meta key) to be translated as escape rendering common M-d, M-w, etc all unseen except for M-del
so the solution is to remap the faulty remapping back to the correct binding.
(global-set-key (kbd "M-C-d") 'backward-kill-word)
Best
