RPN mode

[Voldemar]

I'm learning to use HP Prime in RPN mode. Little by little get to know how to use functions and commands in RPN mode. For the moment I have sense that there are not limitations for using RPN in Home view (in comparison with the Textbook or Algebraic entry modes). Perhaps I am mistaken.
About storing variables in RPN mode. For example, store number 4 in the variable A.
Most known method is similar to HP 50g calculator.
4 Enter Shift ' ' ALPHA A Enter Shift Sto
(9 keystrokes)
But there is another method with using «variable := object» notation.
Shift ' ' ALPHA A Enter 4 Enter ALPHA : Shift = Enter
(12 keystrokes, longer way, but maybe it can be useful in some cases. Variable name must be entered first)
