This is driving me crazy: I simply want Emacs to maximize to whatever screen resolution I have at startup. Ideally I like a cross-platform (Windows & Linux) solution that works on any screen resolution, but I can't even get it to work on just Window XP with even hard-coded sizes. Here are what I tried: Setting the initial-frame-alist with appropriate height/width Setting the default-frame-alist (Windows specific stuff) Sending message to the emacs windows telling it to maximize via (w32-send-sys-command 61488) Tried this function which I found somewhere: (defun toggle-fullscreen () "toggles

How can I create an empty file from emacs, ideally from within a dired buffer? For example, I've just opened a Python module in dired mode, created a new directory, opened that in dired, and now need to add an empty __init__.py file in the directory. If I use C-x C-f __init__.py RET C-x C-s then emacs doesn't create the file because no changes have been made to it. I would have to type in the file, save it, delete my typing and then save it again for that to work. Thanks Here's an adaptation of dired-create-directory . It works the same way, so as well as a plain filename, you can also specify

Sometimes when I open Emacs, Emacs initialization fail. That is because .emacs or init.el files have a bug. (My bugs often come from just mistyping.) I want to find the bug in .emacs or init.el . Is there any way to do this? Drew To find out what part of your init file ( ~/.emacs ) is causing the behavior you see, bisect your init file recursively : First comment-out half, to see which half is responsible, then 3/4, to see which quarter is responsible,... To comment out a region of text (e.g. succession of lines that you have selected), I recommend comment-region (which I bind to C-x C-; ).

My windows configuration looks like this: +----------+-----------+ | | | | | | | | | | | | | | | | +-----------+ | | | +----------+-----------+ And I use the lower right window for special displays (like help, completion etc.), but emacs insists on using that window when I call commands ( find-file-other-window , etc.) that use display-buffer , and resize that window as well. It's annoying... Is there a way that I can force emacs NOT to use that windows? I was thinking of advising display-buffer , but it's a function in c. Any thoughts on this? EDIT: Based heavily on Trey's answer, this is

This question already has an answer here: Eclipse-like Line Commenting in Emacs 7 answers I know there's already an Emacs question on this, and that it was closed, but I find it quite relevant and important. Basically, I want to comment/uncomment the current line. I was expecting this to be fairly easy with a macro, but I found that it really isn't. If the current line is commented, uncomment. If it is uncommented, comment it. And I would also to comment out the whole line, not just from cursor position. I tried a macro like this: C-a 'comment-dwim But this only work to comment a line, not to
