emacs create new file with ido enabled - emacs

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.

How to make speedbar list the C functions + Unable to use sr-speedbar+macro+command history

I am new to Emacs on Windows XP and have multiple queries which I could not find/understand after a lot of search.
I understand that speedbar will support showing of C functions list. As mentioned in http://stackoverflow.com/questions/259364/how-do-i-configure-emacs-speedbar-for-c-sharp-mode, I added the code in .emacs as
(speedbar 1)
(add-to-list 'speedbar-fetch-etags-parse-list
'("\\.c" . speedbar-parse-c-or-c++tag))
I see the speedbar startup but it never shows the functions. Maybe I need to install etags but cannot find it. I also found gtags but could never find a binary
I copied sr-speedbar.el in ~/emacs.d/ directory. I added (require 'sr-speedbar) in .emacs, commented out speedbar related code, reloaded M-x ~/.emacs but did not find any sr-speedbar. If I uncomment speedbar code and comment sr-speedbar, it shows the speedbar on loading. Emacs is able to find sr-speedbar.el in ~/emacs.d/ directory since if I change filename, it shows an error: unable to find sr-speedbar.
I wanted to make a keyboard macro for logging using tramp and ssh. However, when I record a macro, I have to delete multiple characters to provide the path from the beginnig i.e. emacs automatically shows the last path and so I have to delete all the characeters and then start again with ssh://. The keyboard macro records all backspaces and returns error if the backspaces are more than the length of the current path. Is there a way to avoid it
I configured linum package. I want it to start at the beginning of emacs session automatically with typing M-x linum. How can I do that?
Is there way to retrieve command history (not shell commands) and then replay some command
Thanks again for patience on reading until the point :-)
For C, C++, and other languages, supported by CEDET/Semantic, the Speedbar is able to show functions & other objects. But you need to setup Semantic correctly, for example, you can use my article in CEDET.
As I understand, to enable linum-mode globally, you need to put (global-linum-mode 1) into your ~/.emacs
For 3, there are two options:
just type "/ssh:blabla" at the end of the pre-inserted directory (this directory will be ignored as witnessed by it becoming grey).
do C-a C-k to erase the content of the minibuffer.
For 5, there is repeat-complex-command bound to C-x ESC ESC and there is repeat bound to C-x z.

How to work out which package is unsetting keybindings?

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.

Emacs ido-mode and creating new files in directories, it keeps changing the directory while I'm typing

When using ido-mode in emacs, it tends to get in my way when I'm trying to create a new file inside a directory, using: C-x C-f ( start typing a new filename, which doesn't yet exist ) RET
Ordinarily this should create a new file, but when I have ido mode, I have to type the new filename really quickly, otherwise ido-mode decides to move me into a directory that has a file with a matching name, causing me to open that file, instead of creating a new file.
Does anybody know how to force ido-mode to avoid looking in directories other than the one you're currently in?
You can disable the merging (the "looking in other directories" in ido vulgo) with
(setq ido-auto-merge-work-directories-length -1)
but you can also undo the merge with C-z in ido.
Doing this really helps. Basically use ido-mode up until you get to the correct directory, then hit C-f again to get out of ido-mode as you type the new filename.
C-x C-f navigate to directory C-f enter new filename RET.
Use C-j to tell ido to input what you have typed rather than the first completion. This is also mentioned on emacswiki.

How can I more easily switch between buffers in Emacs?

I've recently started using emacs and I'm enjoying using it for the most part. The only thing I'm not enjoying, is switching between buffers. I often have a few buffers open and I've grown tired of using C-x b and C-x C-b, are there any packages that make switching between buffers easier? I've looked into emacs wiki on switching buffers and I'd appreciate insight/feedback on what are are using/enjoying. Thanks.
UPDATE: iswitchb-mode is obsolete in Emacs >= 24.4, replaced by ido.
All of the features of iswitchdb are now provided by ido. Ross provided a link to the documentation in his answer. You can activate with the following in your .emacs (or use the customization interface as Ross suggests):
(require 'ido)
(ido-mode 'buffers) ;; only use this line to turn off ido for file names!
(setq ido-ignore-buffers '("^ " "*Completions*" "*Shell Command Output*"
"*Messages*" "Async Shell Command"))
By default, ido provides completions for buffer names and file names. If you only want to replace the features of iswitchb, the second line turns off this feature for file names. ido will ignore any buffers that match the regexps listed in ido-ignore-buffers.
The behaviour described below for iswitchb-mode applies equally to ido for switching buffers.
iswitchb-mode (Emacs < 24.4)
iswitchb-mode replaces the default C-x b behaviour with a very intuitive buffer-switching-with-completion system. There are more sophisticated options, but I've never needed more than this.
After you hit C-x b, you are presented with a list of all buffers. Start typing the name of the buffer you want (or part of its name), and the list is narrowed until only one buffer matches. You don't need to complete the name, though, as soon as the buffer you want is highlighted hitting enter will move you to it. You can also use C-s and C-r to move through the list in order.
You can turn it on by default with this in your .emacs:
(iswitchb-mode 1)
You can also tell it to ignore certain buffers that you never (or very rarely) need to switch to:
(setq iswitchb-buffer-ignore '("^ " "*Completions*" "*Shell Command Output*"
"*Messages*" "Async Shell Command"))
You can use C-x <right> (next-buffer) and C-x <left> (previous-buffer) to cycle around in the buffer ring. You could bind S-<right> and S-<left> to these functions. (S is the "super-key" or windows-key). This way you can save some keystrokes.
Moreover, note that C-x b has a default entry, i.e. it displays a standard value (most of the time this is the previously viewed buffer), so that you don't always need to enter the buffer name explicitly.
Another nice trick is to open separate windows using C-x 2 and C-x 3. This displays several buffers simultaneously. Then you can bind C-<tab> to other-window and get something similar to tabbed browsing.
M-x customize-group ido then set Ido Mode to Turn on both buffer and file and set Ido Everywhere to on. Then click the Save for future sessions button at the top and enjoy ido magic for both files and buffers. Read the docs to get a sense of how to use ido.
Also, take a look at smex.
ido-mode provides an efficient way to switch buffers.
ibuffer is best for managing all opened buffers.
anything is good for selecting an interested thing from different
sources. (for eg: a single key can be used to switch to another
buffer or to open recently closed file or to open a file residing
in the same directory or ... anything you want ... )

How to invoke the buffer list in Emacs
My toolkit consists of ibuffer, windmove+framemove, winner-mode, and a custom binding to make C-xleft/right and C-cleft/right less of a hassle to use.
I have mapped the "ยง"-key to 'buffer-list and I find it to be very efficient.
I've started using anything for a couple of days and I'm really liking it: http://www.emacswiki.org/emacs/Anything .
Emacs-fu has an good intro to anything: http://emacs-fu.blogspot.com/2011/09/finding-just-about-anything.html
My favourite function for this is helm-mini which is part of helm.
As other helm functions, it allows incremental narrowing of the selection. It also searches your recently visited buffers, which is a really nice way to re-open a buffer. Helm can be a little surprising at first and as a new Emacs user, I found it visually overwhelming and I preferred ido or ibuffer which have been suggested in other replies. But now I absolutely love it and use it all the time for countless things.
Something that I realized by accident and that can be useful:
mouse-buffer-menu is by default bound to <C-mouse-1> (Control key + mouse left click) and opens a popup with a list of the current buffers.

emacs icicles delete selection mode

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.
