title: FreePascal : ValueListEditor manipulation
body: <p>I have a Valuelisteditor that looks like this</p>
  
  <pre><code>Key   |  Name  |
  ---------------|
  Car   |  Audi  |
  Nick  |  Yummi |
  Age   |  70    |
  </code></pre>
  
  <p>and I want to modify the key "Nick" in Row 2 and keep the Name "Yummi".<br>
  I do not want to rewrite the whole row. <br>
  I just want to change "Nick" in "Nickname".<br>
  <br>
  How can I do this in one strike?</p>
