This is a short description of how to use Emacs. Emacs be found on http://www.gnu.org/software/emacs/emacs.html but that doesn't seem to be that updated, and no Windows-version is found. Try Xemacs instead: http://ftp.us.xemacs.org/ftp/pub/xemacs/xemacs-21.4-windows/
Emacs is used to edit textfiles, especially program code.
Notaion: Meaning:
^x keep control down and press x
M-x keep left alt down and press x
OR press escape and then x.
Search: ^r (backwards) ^s (forwards).
Type some letters afterwards.
Press ^r or ^s many times if you want!
Edit: ^space AND THEN ^w cuts the text between the two
places you typed that on.
^k deletes the rest of the raw. It can be used many
times at ones and if you don't move between the ^k:s
all the deleted text will be in the same paste-buffert.
^y (yield) will insert all the copied or cut text.
Commands: M-x gives you a minibuffer at the button of the page
that you can use to find a command. Press tab for all
commands.
Panic: ^g stops the current command. Good if you have a minibuffer
that you don't want to use.
Undo: ^_ undoes the last command. Can be pressed many times. Can also undo
undoings if you move after the last undo.
No command: Press ^q to make the next pressing of ^something to not be
interpreted as a command.
Save: ^x^s saves the current file in the same name.
& ^x^s saves the current file in another name.
load: ^x^f loads a new file.
Moving: ^a (anfang?) moves to the beginning of the raw.
^e (end) moves to the end of the raw.
M-a moves to a more endish end... (depending on mode)
See: ^l makes the cursor to be in the middle of the window.
Upper: M-u makes the rest of the word in upper case
Lower: M-l makes the rest of the word in lower case
Replace: M-x replace-string and M-x query-replace makes it possible
to replace a string everywhere (from the current position).
Mode: M-x c-mode gives you the c-mode.
M-x fundamental-mode gives you the fundamental-mode.
Buffert: A buffert is a text. You can change between them with
^x b. (Use tab to list all of them!)
You can also reload texts with the ^x^f command and use
arrow up to reload the last files.
M-x kill-buffert removes the current buffert from your
current emacs-session.
