Vi is a very good and popular editor under Linux. I was not a big fan of it before, but after a few years of using it. Finally I felt it is better than emacs in general. Here is a configuration file(~/.vimrc) that I am using now.

In normal mode:

In Visual Mode:

= indent selected area(very useful)

My .vimrc file

"set up the back up dir
let myuid=substitute(system('id'), '^uid=\([0-9]*\)(.*', '\1', "")
let vimtdir=$HOME . '/vimtmp'
if isdirectory(vimtdir) == 0
   let vimtdir=$HOME
endif
if myuid == "0" && osys =~ "SunOS"
   let vimtdir='/var/vimtmp'
endif
set backup
let &backupdir=vimtdir

Emacs is very powerful, but I only use it as a editor. Here is the configuration file(~/.emacs) I am using now. I got most parts of it from the internet. I put them here so next time when I want them, I don\'t have to google again. I feel it easy for people from Windows to learn this than vi. Just need to remember about 5 key combinations, then you can start. So it really fit for people from Windows
CTRL+x CTRL+f: open file. The cursor should go to the last line, status bar. then just input the file name.
CTRL+x CTRL+s: save file.
CTRL+x CTRL+c: exit emacs, it will ask you to save files if any files are changed.
CTRL+s: search, after input the string you want to search, continue press CTRL+s will find all in the current buffer.

In Windows, my favorite editor was UltraEdit, which is super powerful, column mode, edit remote files... It can do everything and everybody can fall in love with it if he/she is willing to pay. But now I love Notepad++ more. It is also powerful, light weight and full of features. I like it's coding style more than UltraEdit. And it is free!

Here is the configuration files for emacs and vi/vim(only used them in Linux/UNIX although they all have windows versions)
