I tried out Sublime Text 2 recently, and I found Goto Anything superbly useful for navigating source code ( Ctrl-P file@symbol seems to work really well). Is there something similar for Emacs? Preferably something that just works, without a ton of custom elisp. What I've tried so far: I've seen Helm and Anything , but as far as I understand neither of them is capable of actual "instant" search (see edit below). I've used multi-occur-in-matching-buffers , but it too seems unable to satisfy the "instant" criterion. imenu / idomenu works well for single files, but doesn't work across files. I

I am using prelude as a base Emacs configuration. I have installed lots of packages from the package manager, and I want to use my settings on another machine. I don't want to carry the installed packages and also I don't want to create a list manually. What is the way of saving a list all the installed packages into prelude-package.el or any other file so that when I take this configuration to my other machine, they automatically get installed there on first use? ataylor You can get a list of currently installed packages (excluding built in packages) from the variable package-activated-list .

When running emacs in daemon with a client and I hit C-x k, it says: Emacs buffer still has clients. Are you sure you want to quit? But when using C-x #, it exits immediately. I don't understand the difference. Why doesn't C-x k just behave normally in the first place, if its in a client? I found this snippet that's supposed to make C-x k behave properly but I don't understand the difference. Furthermore, when an emacs client starts up, it starts with the previous buffer for a few seconds then opens up the new buffer. Isn't the point of emacs server to speed up the initial start up time? Why

Follow up to: Emacs org-display-inline-images I managed to show inline images following abo-abo's advice. Now I want to set a fixed width size for all of them. Setting (setq org-image-actual-width 50) didn't work. Emacs picked the variable, but it isn't doing anything to the images. The idea is to show them as thumbnails. Note: I am using emacs 24.2 on Linux. I can show thumbs using M x image-dired, however, I want to show fixed size images under org mode. Normal images can already be shown. I've looked at org-display-inline-images source: it's just calling create-image . It seems there's no

Can anybody explain me how eval works with emacs24? From eval description: eval is a built-in function in `C source code'. (eval FORM &optional LEXICAL) Evaluate FORM and return its value. If LEXICAL is t, evaluate using lexical scoping. Does that mean, that something like this should work? (setq lexical-binding t) (let ((myvarr 42)) (eval 'myvarr t)) ; (void-variable myvarr) Update: (setq lexical-binding nil) ;; => nil (let ((myvarr 42)) (eval 'myvarr)) ;; => 42 (#o52, #x2a, ?*) (setq lexical-binding t) ;; => t (let ((myvarr 42)) (eval 'myvarr)) ;; Debugger entered--Lisp error: (void-variable

I try to add a button in the tool-bar but that doesn't works. how to do that, i check in Emacs wiki and i find nothing. I used emacs 24.3.1. The toolsbar are displayed but not my new item. I can run it with eval-buffer but not with my .emacs or find another solution to resolve that. When i add it with eval-buffer my button leave my toolbar after a scroll. (defun omar-hotel () "another nonce menu function" (interactive) (message "hotel, motel, holiday inn")) (define-key global-map [tool-bar omar-button] '(menu-item "Hotel" omar-hotel :image (image :type xpm :file "/usr/share/emacs/24.3/etc
