List of commands for PCD8544 library

I just started using this library for a NOKIA 5110. Everything works great, however I'm sure there are more commands available than what I am using in the example.
Any suggestions?
Yes, I will try using different libraries as well, it's just that I am using this one presently.

Have a look at the library .h and .cpp files in an editor and any examples that came with the library in the IDE
