====== Vim Tutorial ======
===== Opening Vim =====
A plain ol' vim opening
<cli> lab46:~$ vim </cli>

To open a file in vim with the filename file
<cli> lab46:~$ vim file </cli>

The -o option adds the ability to open mutliple windows at once.  N is the number of windows to open. Replace -o with -O if you want to open the windows vertically. This can also be done with previously saved files. Omit the N and enter the file names after the -o.
<cli> lab46:~$ vim -oN </cli>

===== Saving in Vim =====
  * :q - exit with file unchaged
  * :q! - exit and discard any changes to file
  * :wq or :zz - save and quit - If you didn't specify a filename upon opening vim add the desired filename to either of these.

  *esc - enters command mode
  *i - input mode - cursor at current position
  *a - append - cursor at next character position
  *o - places the cursor on the next line
  *O - places the cursor on the previous line
