There are apparently no fade markers, but if you chose a default transition, you can add it to a title by selecting the clip and hitting ctrl-T (on a PC, anyway). This will put the transition on both the in/out points. If you want it on one side only, select the cut point with "v" and use the "u" key to select left, center or right, then hit ctrl-T (assuming your choice of position has content to fade in/out).
You can also copy a transition from one clip to another, by holding down alt and dragging the transition to the new clip.
