I used to be able to undo actions all the way until a file was opened. Recently, I've been unable to do that, and I'm unable to undo actions beyond a certain point, which seems random, but might be related to the undo buffer size.
I was just wondering if anyone might have come across this problem, and if there might be a solution.
To prevent confusion, I only run one "window" of emacs and so I use window in the emacs sense. I'm looking to get a window split which, let's say 70 in width, contains the completions buffer on the new split when I start emacs. I think I need to have a dedicated window.
In Emacs, how do I inspect what has been modified in a buffer (before saving and overwriting the file)?
(In a sense, the requested action is an analog of git status and git add -i showing what has been modified, only the comparison should be done between the buffer contents (in Emacs's memory) and the file on disk.)
Sometime, I forget what has been modified in a buffer, and would like to call a
I am using Linux Fedora 13 (Constantine) and emacs 23.1.1. I am trying to set up a .emacs file for initialization, by using emacs itself to edit and save a file .emacs in my home directory. However, although the file is there, emacs does not seem to recognize it.
I encountered a rather strange problem when using nano in general. When using the undo/redo shortcuts it just says "Nothing in undo buffer!" and nothing happens. Yeah, that's it. Anyone an idea how get undo/redo working in nano?
