title: Configure Eclipse string externalization wizard that value is used as key
body: <p>I use Eclipse to externalize my language dependent strings.
  How can I change its default behavior in the following way:</p>
  
  <p>In the default the keys are numbered 0 .. n.
  I would like the key to be the value. 
  Even better would be if the key would be the value and all spaces replaced by "_".</p>
  
  <p>If a configuration is not possible I would like to program it myself. Could anyone point me to the starting point (the source of eclipse) and how I would integrate it once I am done?</p>
  
  <p>Many thanks for any advice.</p>
