I am used to the RPN stack and often use the repeating t register to stream down a constant. For example the multiplication of a series by 2.

I found in the algebraic mode if I keyed 2 X 2 enter, it of coursr gave 4. I entered again, it put the X number in Y and gave me the answer 8. It can be repeated.
