Cleanup

Binds some additional sequences to emacs-backward-word and
emacs-forward-word. The problem is that terminfo doesn't know about
Ctrl+ArrowKeys, so one has to resort to using raw sequences as used
in the wild. The sequences were copied from Debian's /etc/inputrc
(readline configuration), so they should be fairly portable.
It works in xterm and rxvt terminals and doesn't work on
TERM=linux (virtual console) as Ctrl+Arrows send the same sequence
as Arrows alone.

+Fasd
+====
+
+[Fasd][1] is a command-line productivity booster, inspired by tools like
+[autojump][2], [z][3] and [v][4], it offers quick access to files and
+directories by keeping track of files and directories  that were previously
+accessed.
+
+For completion to work, this module must be loaded **after** the *completion*
+module.
+
+The Prezto Fasd configuration differs from the default. The default aliases have
+been disabled.
+
+Aliases
+-------
+
+  - `j` changes the current working directory interactively.
+
+Completion
+----------
+
+Type `,`, `f,`, `d,` in front of a comma-separated query or type `,,`,  `,,f`,
+`,,d` at the end of a comma-separated query then hit <kbd>tab</kbd>.
