Click off the title on another clip (underneath?) then select the Title in the storyline again. Move the cursor up over the text. The text should outline the bounding box and the cursor should change to an arrow with cross arrows on the lower right. Click once on the text. You should get the 3D onscreen control. If you hold down the command key, you'll get an enhanced OSC for rotation (the XY&Z axes will highlight at once and holding down the command key, you can click in the "orb" region to rotate all directions at once.) To edit the text after the 3D controls appear: double click on the text. Once you get the text edit action going, you pretty much have to deselect the title (with the storyline active, Command-Shift-A) then select the title in the storylline again.
Even when you get it "down" - it can still be a little flaky, so be "deliberate" dealing with it.
