title: How to stop Emacs from "contaminating" the clipboard?
body: <p>Emacs always copies killed/deleted content to the clipboard. I often need to copy and paste content into Emacs but when I delete existing content from Emacs before pasting, the content I would like to paste is lost.</p>
  
  <p>The only solution I found is to use</p>
  
  <pre><code>(setq save-interprogram-paste-before-kill t)
  </code></pre>
  
  <p>in order to make sure content copied outside of Emacs stays available in the kill-ring, and people with similar problems seem to be satisfied with this solution. What bothers me about it is that I have to type <kbd>C-y</kbd> <em>followed by one or more repetitions of</em> <kbd>M-y</kbd> to get to the content I want to paste.</p>
  
  <p>So my question is: How can I stop Emacs from copying content to the clipboard when I kill/delete it (excluding cases where I delete a region with <kbd>C-w</kbd>)?</p>
