You can apply transitions, effects and motion paths to titles just as you can any other clip, visionp.
Just make sure you're in Timeline mode so that you can see the title clip. Then you can add fades in or out (right-clicking on the clip) or apply any other transition or effect to it.
If you need help with some of these basic functions, have a look at my free Basic Training for Premiere Elements tutorials on Premiere Elements support site Muvipix.com. I also have a number of books available online that will show you in detail how to work with all of the tools in the program.
Along with the Presets in the Titler, you can add other Transitions from the Transitions/Effects Panel.
You can also create your own, for some types of Transitions, with the use of other Effects, and then Keyframing those Effects with the Edit Effects Panel. I will often create what amounts to Transitions, with the Blur Effects and the Opacity Effect and Keyframes.
