title: [org-mode]: repeating task in every Mon, Wed, Fri at 18:00, need help with sexp
body: <p>As I had written in title, I need a little help with improvement of this sexp:</p>
  
  <pre><code>* TODO remeber about thingie.
    SCHEDULED: &lt;%%(or (= 1 (calendar-day-of-week date)) 
                      (= 3 (calendar-day-of-week date)) 
                      (= 5 (calendar-day-of-week date)))&gt;
  </code></pre>
  
  <p>Now it shows itself in the following days, but I would like to change two things about it:</p>
  
  <ul>
  <li><p>How can I also schedule on specific hours (i.e. 18:00 - 20:00) in the following days</p></li>
  <li><p>How can I made this task repeat itself, just like it repeats itself with </p>
  
  <p><code>&lt;2010-05-13 Wed +1w&gt;</code></p>
  
  <p>(by repetition I mean something like it automatically logs the closing date and time and comes back to the <code>TODO</code> state).</p></li>
  </ul>
  
  <p>I will be grateful for any help.</p>
  
  <p>Thanks.</p>
