title: How to add tags completion to org mode capture?
body: <p>I use org mode's capture functionality to make all my todo's. It is clean and practical and let me add a consistent content to all my todo's, including a prompt for heading, a prompt for tags and an automatic insertion of created date. Here is my code:</p>
  
  <pre><code>(setq org-capture-templates '((
       "t"                ; key
       "Todo"             ; description
       entry              ; type
       (file+headline "C:/.../org/notes.org" "tasks")       ; target
       "* TODO [#B] %^{Todo} :%^{Tags}: \n:PROPERTIES:\n:Created: %U\n:END:\n\n%?"  ; template
       :prepend t        ; properties
       :empty-lines 1    ; properties
       :created t        ; properties
       )))
  </code></pre>
  
  <p>However, my prompt for tags forces me to enter tags from memory. How could I add tags from the tags list set by the following code:</p>
  
  <pre><code>(setq org-tag-alist `(
                ("OFFICE"   . ?o)
                ("HOME"     . ?h)
                ("ERRAND"   . ?e) ))
  </code></pre>
  
  <p>When my point is in the heading of an already created task, this list pops up when I hit C-c C-c and let me chose the tags by their short cut single letters "o", "h" or "e".</p>
  
  <p>So my question is: is it possible to include this pop-up list of tags inside the code for my capture?</p>
