Viper mode for emacs

i enjoy modal editing. there are several packages available 
for emacs that interested me, like:

- god mode
- meow mode
- evil mode
- viper mode

i tried god mode for a while, but moved to meow because the 
name is cute :3

lately i've been learning viper mode, as it comes with GNU 
emacs, and a package is available for xemacs.

so far it is nice. i don't need anything too fancy, i just 
want some basic movement without holding ctrl, but some of 
the vi-isms are nice to have.

--- features of viper --------------------------------------

set a 'text mark' with m[L] (where [L] is a letter), and you 
can jump back to it with '[L] (apostrophe, then a letter). 
you can even jump to a mark in another file.

m.	- set emacs mark
dr	- kill region
dd	- kill line
p	- paste recently killed text
G	- go to end of buffer
3G	- go to line 3
b/w	- back / forward word
B/W	- back / forward symbol (kinda?)
^b/^f	- scroll back / forward a page
z -	- line to top
z RET	- line to bottom
H/L	- window top/bottom

there were some bindings i had to add myself, like:
M-c	- alternative & closer ESC
zz	- save buffer
gg	- beginning-of-buffer

i also set these bindings:

(setq viper-inhibit-startup-message 't)
(setq viper-expert-level '5)

(setq viper-want-ctl-h-help t
      viper-want-emacs-keys-in-vi t
      viper-ex-style-motion nil
      viper-want-emacs-keys-in-insert t)

anyway, i'll see how long it takes me to get bored of this.
