Caption, where to enter text

I have been looking everywhere but cannot find the proper way to enter a caption for a photo. I guess this must be done e.g. in iPhoto but there is no documentation that instructs me how to do this.

If you click + hold the “T” button you get various options regarding titles. PhotoPresenter uses for example titles from iPhoto, the file names etc. You can’t enter titles manually, I’m afraid.

I was wrong, you can set a title for each image individually:

Switch to “Name/Title” via the “T”-button, select an image and click the “i” button (i for inspector). There you can set a title.

I don’t see an I button for the inspector.

Sorry we got it kinda wrong twice. You need to create a “Custom Slideshow” before. I made a short video showing how it’s done:
