That is likely the quickest way to get started.

The keyboard in the picture is the actual keyboard, although you may need to do 
a bit more work to set it up. There is a tool called the Palette in the Tools 
menu that lets you enter all the symbols with mouse clicks without having to do 
any more set-up and without having to learn the key combinations.

If you do want to set up the keyboard have a read of section 4.3 of the Xpp 
manual and the comments at the head of the file app-defaults/XppKeyboard in the 
first instance.

Good luck! And do keep asking if you have any more problems.
