=====Permanently enable syntax highlighting=====
Add to ~/.vimrc:
<code>
:syntax enable
</code>


=====Set default highlighting to 'desert' in system config=====

// Tested on Ubuntu. //

<code>
echo :colorscheme desert >> /etc/vim/vimrc.local
</code>


=====Set default in system config to always show current filename=====

// Tested on Ubuntu. //

<code>
echo :set ls=2 >> /etc/vim/vimrc.local

=====Convert file format from DOS to UNIX=====

To UNIX:
<code>
:set ff=unix
</code>

To DOS:
<code>
:set ff=dos
</code>

=====Replace ^M line endings with UNIX line endings=====

Type:
<code>
:s/Ctrl+VCtrl+M/\r/g
</code>

The replace will then look like this:
<code>
:s/^M/\r/g
</code>

=====Replace curly double-quotes=====

To replace from the current line to the end (,$):
<code>
:,$s/[Ctrl+vu201cCtrl+vu201d]/"/g
</code>
// Ctrl+vu201c means: hit Ctrl+V, enter u201c. //

So that it looks like:
<code>
:,$s/[“”]/"/g
</code>

=====Update ColdFusion syntax highlighting=====

The cf.vim with syntax highlighting supplied with Vim (on OpenBSD) does not highlight cfscript files. \\
To update, replace the highlighting with the cf-utils.vim from GitHub.

  - Download the last version from [[https://github.com/camgunz/cf-utils.vim|GitHub - davejlong/cf-utils.vim
]] via the "Download ZIP/TAR.GZ" button on the right.
  - Unpack the archive.
  - Copy the contents of the cf-utils.vim-<hash> directory to ~/.vim/:<code>mkdir ~/.vim/ && cp -R cf-utils.vim-15088cfad92f0e01d8d6c62e8804828f5adf8bd6/* ~/.vim/</code>
  - Start vim and open a .cfm file from ~/.vim/examples/ to test.
  - The code should be highlighted in colors.

=====Disable mouse support=====
// Tested on Debian 9 with VIM 8.0 with included patches: 1-197, 322, 377-378, 550. //

Disable mouse support so you can copy and paste the way I'm used to by commenting the "if has ('mouse')" statement in /usr/share/vim/vim80/defaults.vim.

Unified diff patch to do this:
<code>

+++ /usr/share/vim/vim80/defaults.vim   2017-07-25 09:57:42.009742204 +0200
@@ -66,9 +66,9 @@

 " In many terminal emulators the mouse works just fine.  By enabling it you
 " can position the cursor, Visually select and scroll with the mouse.
-if has('mouse')
-  set mouse=a
-endif
+"if has('mouse')
+"  set mouse=a
+"endif

 " Switch syntax highlighting on when the terminal has colors or when using the
 " GUI (which always has colors).

Or just do the following which is simpler and less invasive:
<code>
echo :set mouse= >> ~/.vimrc
</code>


=====Recording=====

Start recording:<code>q+LETTER</code>
End recording:<code>q</code>

To disable recording add the following to .vimrc:<code>map q <Nop></code>
