Not quite. The HIST key activates the interactive stack while in Input forms like TVM or numerical solver.

Also, it is useful in Algebraic mode as you need the HIST key to access entries in the stack while the command line is active.

interesting features that I did not know, but I still have the doubt that you could put a "HIST" in the function keys at the time of editing, or apply the same functionality to the up arrow key as it is in the 48 series (!)

Quote:The Up Arrow does allow one to move up the stack, but the HIST key (at lease as I use it) recalls some stuff even with an empty stack. I'll have to check these out a bit more. I found most of this stuff by experimentation.

with the empty stack HIST always gives me an error ...
