+" Description: A minimal, but feature rich, example .vimrc. If you are a
+"              newbie, basing your first .vimrc on this file is a good choice.
+"              If you're a more advanced user, building your own .vimrc based
+"              on this file is still a good idea.
+
+"------------------------------------------------------------
+" Features {{{1
+"
+" These options and commands enable some very useful features in Vim, that
+" no user should have to live without.
+
+" Set 'nocompatible' to ward off unexpected things that your distro might
+" have made, as well as sanely reset options when re-sourcing .vimrc
+set nocompatible
+
+" Attempt to determine the type of a file based on its name and possibly its
+" contents. Use this to allow intelligent auto-indenting for each filetype,
+" and for plugins that are filetype specific.
+if has('filetype')
+  filetype indent plugin on
+endif
+
+" Enable syntax highlighting
+if has('syntax')
+  syntax on
+endif
+
+"------------------------------------------------------------
+" Must have options {{{1
+"
+" These are highly recommended options.
+
+" Vim with default settings does not allow easy switching between multiple files
+" in the same editor window. Users can use multiple split windows or multiple
+" tab pages to edit multiple files, but it is still best to enable an option to
+" allow easier switching between files.
+"
+" One such option is the 'hidden' option, which allows you to re-use the same
+" window and switch from an unsaved buffer without saving it first. Also allows
+" you to keep an undo history for multiple files when re-using the same window
+" in this way. Note that using persistent undo also lets you undo in multiple
+" files even in the same window, but is less efficient and is actually designed
+" for keeping undo history after closing Vim entirely. Vim will complain if you
+" try to quit without saving, and swap files will keep you safe if your computer
+" crashes.
+set hidden
+
+" Note that not everyone likes working this way (with the hidden option).
+" Alternatives include using tabs or split windows instead of re-using the same
+" window as mentioned above, and/or either of the following options:
+" set confirm
+" set autowriteall
+
+" Better command-line completion
+set wildmenu
+
+" Show partial commands in the last line of the screen
+set showcmd
+
+" Highlight searches (use <C-L> to temporarily turn off highlighting; see the
+" mapping of <C-L> below)
+set hlsearch
+
+" Modelines have historically been a source of security vulnerabilities. As
+" such, it may be a good idea to disable them and use the securemodelines
+" script, <http://www.vim.org/scripts/script.php?script_id=1876>.
+" set nomodeline
+
+
+"------------------------------------------------------------
+" Usability options {{{1
+"
+" These are options that users frequently set in their .vimrc. Some of them
+" change Vim's behaviour in ways which deviate from the true Vi way, but
+" which are considered to add usability. Which, if any, of these options to
+" use is very much a personal preference, but they are harmless.
+
+" Use case insensitive search, except when using capital letters
+set ignorecase
+set smartcase
+
+" Allow backspacing over autoindent, line breaks and start of insert action
+set backspace=indent,eol,start
+
+" When opening a new line and no filetype-specific indenting is enabled, keep
+" the same indent as the line you're currently on. Useful for READMEs, etc.
+set autoindent
+
+" Stop certain movements from always going to the first character of a line.
+" While this behaviour deviates from that of Vi, it does what most users
+" coming from other editors would expect.
+set nostartofline
+
+" Display the cursor position on the last line of the screen or in the status
+" line of a window
+set ruler
+
+" Instead of failing a command because of unsaved changes, instead raise a
+" dialogue asking if you wish to save changed files.
+set confirm
+
+" Use visual bell instead of beeping when doing something wrong
+set visualbell
+
+" And reset the terminal code for the visual bell. If visualbell is set, and
+" this line is also included, vim will neither flash nor beep. If visualbell
+" is unset, this does nothing.
+set t_vb=
+
+" Enable use of the mouse for all modes
+if has('mouse')
+  set mouse=a
+endif
+
+" Set the command window height to 2 lines, to avoid many cases of having to
+" "press <Enter> to continue"
+set cmdheight=2
+
+" Display line numbers on the left
+set number 
+
+" Quickly time out on keycodes, but never time out on mappings
+set notimeout ttimeout ttimeoutlen=200
+
+" Use <F11> to toggle between 'paste' and 'nopaste'
+set pastetoggle=<F11>
+
+
+
+"------------------------------------------------------------
+" Indentation options {{{1
+"
+" Indentation settings according to personal preference.
+
+" Indentation settings for using 4 spaces instead of tabs.
+" Do not change 'tabstop' from its default value of 8 with this setup.
+set shiftwidth=4
+set softtabstop=4
+set expandtab
+
+" Indentation settings for using hard tabs for indent. Display tabs as
+" four characters wide.
+"set shiftwidth=4
+"set tabstop=4
+
+
+"------------------------------------------------------------
+" Mappings {{{1
+"
+" Useful mappings
+
+" Map Y to act like D and C, i.e. to yank until EOL, rather than act as yy,
+" which is the default
+map Y y$
+
+" Map <C-L> (redraw screen) to also turn off search highlighting until the
+" next search
+nnoremap <C-L> :nohl<CR><C-L>
+
+nnoremap n nzzzv
+nnoremap N Nzzzv
