With a QuickTime file open QuickTime Player, and an OmniOutliner file open that matches the title below, if this is invoked:

- If the QT file is playing, it is paused and the current playback speed is recorded (use option-click on the fast forward button to increase playing speed in QuickTime Player)
  - If there is not a row starting with the right session number, one is created at the top level (with a link back to the QT file)
  - A new row is added with the current time code and the insertion point to the right of it and OmniOutliner is activated.
  
- Otherwise, playing in the QT file is resumed a couple seconds before the point at which it was paused, with the playback rate restored, and QT is activated

- Setup:
