When I use the Command in Auctex C-c C-c, it brings up a list of possible commands. It will usually select a reasonable default (e.g. Command: (default View)), however, when I press RET, it selects whatever is selected in the list below. I suspect this behavior is caused by one of the following packages I have installed
flx-ido
ido-ubiquitous
ido-vertical-mode
smex
To be honest, I used pieces from others' .emacs, so I'm not sure which of the customizations are causing this.
You do not have to deactivate it. You can type C-j to accept the current entry. If the current entry is empty, it will select the default.
It was ido-ubiquitous. Deactivating fixed it

I am currently using spacemacs with auctex. When I use reftex-toc and goto an item then it performs a vsplit and shows the content in the right window. How do I prevent this splitting behaviour? I would like it to open in the current buffer from which the command was issued.
It is related to reftex-toc.el.
I added this hook to maximize the newly opened window:
(add-hook 'reftex-toc-mode-hook 'spacemacs/toggle-maximize-buffer)
but it is a suboptimal solution, as it influences other splits I might have made.
What you describe could be related to the way you select an item.
In normal Emacs (not Spacemacs), I see that SPC is bound to reftex-toc-view-line which behaves just how you describe it. But RET is bound to reftex-toc-goto-line-and-hide which seems to do what you want.
Maybe you just need to find out where that function is on your keymap.
There are always links in help-mode which suppose to be entered by the <return> button. Since I remapped the <return> button to indent-and-new-line, I can no longer enter the link. I would like to find the correct key map for the enter button.
Help mode defined in `help-mode.el' (`help-mode'):
Major mode for viewing help text and navigating references in it.
Entry to this mode runs the normal hook `help-mode-hook'.
Commands:
key binding
--- -------
C-c Prefix Command
TAB forward-button
(that binding is currently shadowed by another mode)
RET help-follow
(that binding is currently shadowed by another mode)
ESC Prefix Command
SPC scroll-up-command
I get this help from the describe mode. I tried the help-follow but it does not work. What should be the correct key bind?
By default RET runs push-button when on a link in help-mode. You should also be able to click on links with your primary mouse button if you like using the rodent. This function is not bound to any other keys out of the box.
I'm not sure how you're rebinding RET, but it probably makes sense to do it a bit more selectively. indent-and-new-line might make sense in most modes, but as you have discovered there are situations where you may want the default behaviour.
Perhaps you could do this via prog-mode-hook, so it only affects programming modes?
Alternatively you could bind some other key to push-button in help-mode.
By the way, here is a useful technique that would have let you discover this keybinding yourself:
Run Emacs with the -Q flag to suppress loading of your init file and the system init file.
Activate a buffer that uses help-mode, e.g. by using C-h f message RET to see the documentation for the message function and then C-x o to switch to the help window.
Press C-h k RET to see what function is bound to RET.
I must be stupid, but I just switched to Emacs 24, and holding Shift while moving the point no longer highlights text. Mouse selection works as before. What am I missing? Did I turn it off by chance? Or has Shift selection been deemed unergonomical so we have some other, better keyboard-based selection at hand?
Shift selection is enabled by default in Emacs 24.
You can always run emacs -Q to disable your init file and any other default libraries, in order to determine what Emacs' default behaviour is.
You can also run emacs -q which will disable only your init file (other system-wide init files can be loaded).
If the feature works without your init file and does not work with it, you can then start to narrow down what part of your init file is at fault (often by commenting out functionality until the feature starts working as expected -- note Drew's comment).
In this case I suggest that you firstly verify (using C-hv) that the shift-select-mode variable is non-nil (when running with your normal configuration), as a nil value means that shift selection is disabled.
I also found it useful to look at load-path variable, C-h v load-path, which directed me to the culprits, old elpa packages.
I have a directory "a" with a set of templates, for instance
$ ls a
b bcc cc ccdd
I would like to implement a keyboard shortcut in Emacs that will show a buffer with the template names, similar to dired or buffer-menu and then be able to select a template name by using arrow keys or mouse. Then insert the selected template into the current buffer at point.
How can this be done?
To augment Chris' answer with a little code, here is a small wrapper around ido-insert-file:
(require 'ido)
(defvar so/template-directory "/tmp/templates"
"Directory where template files are stored")
(defun so/insert-template ()
(interactive)
(let ((default-directory so/template-directory))
(ido-insert-file)))
This allows you to run (or bind a key to) so/insert-template no matter what directory you are currently in. Obviously set so/template-directory to your preferred directory.
insert-file, bound to C-x i by default, can insert a file into your buffer at point, but it doesn't give you a nice menu. Both helm and ido enhance this behaviour.
helm does not come with Emacs, but it can be installed via MELPA. When helm-mode is active, insert-file uses Helm's narrowing features. Once you're in the a directory, the up and down keys may be used to select a file, and Enter will insert it.
ido is shipped with Emacs. When ido-mode is active, C-x i is rebound to ido-insert-file. Once you're in the a directory, the left and right keys may be used to select a file, and Enter will insert it.
Both tools are excellent, both can be used in many other situations, and both offer effective filtering and navigation. Try one or both and use whichever you prefer.
Everything #Chris said about Helm and Ido is true also for Icicles, and with better "narrowing" features and on-the-fly sorting in different orders.
There is nothing extra to do --- just load Icicles and turn on Icicle minor mode. Whenever you use standard command insert-file (bound to C-x i) you get the behavior you requested for free. This behavior is in fact available for all completion in Emacs. In Icicle mode, standard commands become menus you can use the arrow keys on, etc.
In addition, your question title asks to be able to "select a set" of files. You can do that easily in Icicles, but not otherwise. IOW, selection is also multi-selection.
(However, I suspect that your question is mistitled, since the text describes something different, and I doubt that you want to insert a set of files. You probably meant that you want to select one file name from a set of file names. Consider retitling the question, if so.)
Is there a key binding to quit a mode and return to the previous mode in emacs?
For example suppose I entered line number mode using the following command:
Alt+x linum-mode
How can I quickly disable this mode and return to the mode which I was in before (not using the same command again)?
Why wouldn't you want to use the same command again?
M-xM-pRET
It doesn't get much simpler than that.
Edit: You can repeat M-p in that sequence to step back further in the command history, and you can search the command history with M-xC-r.
Also, when you disable a minor mode you're not "returning to the mode you were in before"; you're just disabling one (of many) minor modes which are all active at the same time.
Tangentially, the concept of "returning to the mode you were in before" could apply to major modes (as there's only ever one active major mode in a given buffer), but strictly speaking there's no notion of 'disabling' a major mode -- only of 'enabling' the one you wish to change to -- so to 'toggle' between two major modes, you would need to call them alternately.
Just repeat the same command: M-x linum-mode. Such minor-mode commands are toggles: on/off.
C-x z calls repeat - repeat last command.
Repeatedly calling a minor-mode enables/disables it.
One more way to do it is with smex: the last command
that you called with M-x kinda sticks around.
So you can enable linum-mode with smex, do a bunch of editing
with usual shortcuts and then disable linum-mode with
M-x RET.
A solution might follow the path kill-ring-save works: store the modes being active as current-modes-listing in a previous-modes-ring.
The code needed therefor exists basically inside describe-mode, see upward from "Enabled minor modes" - respective for the major mode.
Then a hook should check if this-command has "-mode" in it's name. If yes, check, if current modes-listing equals car of previous-modes-ring. If not, add new setting.
Finally write a command which sets current modes according to selected listing from previous-modes-ring.
