That's great, I assume that the individual values of the lists will be usable as separate numbers on the stack, so I could go to one of them and press enter, and that single number would be brought to the current calculation line?

Thanks for the reply.

And see this thread. https://www.hpmuseum.org/forum/thread-16946.html

A user defined key can return a string containing multiple values space separated to the command line. Pressing Enter will place those values as separate numbers on the stack.

In the code below, userkey Shift User 2 will place 4 3 2 1 on the RPN command line. Pressing Enter will place the following into Stack levels 1-4

4 (stack 4)
3
2
1 (stack 1)

Code:


KEY K_2()
BEGIN
RETURN "4 3 2 1";
END;
