title: How to add a new string to a *.po file w/ a PO editor
body: <p>I MANUALLY created a file: test.po with the contents:</p>
  
  <blockquote>
    <p>msgid "greeting"<br>
    msgstr "Hello World"</p>
  </blockquote>
  
  <p>Now I can edit the translation (hello world) in editors like "poedit" and "GTranslated" (I'm using Ubuntu). I can even add comments to that translation. However neither "poedit" and "GTranslated" will let me ADD a new translation string - I've looked online to no avail and looked at screenshots of other editors and none seem to have a "new" button.</p>
  
  <p>What am I missing??? It seems stupid to have to edit new keys w/ a "plain" text editor and then edit them in these PO editors (whichever they may be). (If you can't tell I'm new to this 'gettext' world - I'm building a website in Zend/PHP.)</p>
