title: Emacs: Insert tab instead of spaces
body: <p>For several reasons I prefer to configure my editor to insert spaces when <kbd>TAB</kbd> is pressed.</p>
  
  <p>But recently I discovered that tabs should remain as tabs in make files.</p>
  
  <p>How do I insert tab (<code>\t</code>, not <code>"    "</code>) without reconfiguring editors each time I need to write make files?</p>
  
  <p>I use the following editors:
  <a href="http://en.wikipedia.org/wiki/Emacs" rel="noreferrer">Emacs</a>, <a href="https://en.wikipedia.org/wiki/Kate_%28text_editor%29" rel="noreferrer">Kate</a>, <a href="http://en.wikipedia.org/wiki/Gedit" rel="noreferrer">gedit</a>, and the <a href="http://en.wikipedia.org/wiki/Microsoft_Visual_Studio" rel="noreferrer">Visual Studio</a> editor.</p>
