is the stack general purpose accepting all kinds of object including functions and equations?
are there stack manipulating keys/commands : depth, roll, roll down ..?

Have a look at Chapter 3 of the User Guide. However it only covers the basic stack operations, not how to use it with commands & functions, which may or may not be obvious.

Most of the stack operations are soft keys. I think the only dedicated hard key is Swap (on the key to the left of Enter).
