Edit mode on xtreme photo

  Quoted text:

  [ First you need to split the audio from the video. Highlight the video in edit mode. Click on the "ungroup" button (broken chain symbol) or press CRTL + M. Now you can shorten the video without affecting the sound track. If you need to fade in and out select the point in the audio you want to fade at, Choose the "cut" symbol (razor blade) and you will have editable sections of music. I split the music where I want to insert a voice-over and fade the music to low, then insert the voice track below in the faded out section (use a new track for this. At the end of the voice over fade the music back up.]

How do I get into 'edit mode'? I see only storyboard, overview and timeline modes.

Anyone??
