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.

You are right.
I just checked.
When in input form pressing up arrow just moves to the upper input field, while pressing HIST gives access to interactive stack and makes possible to pick objects from stack to input form.
I never discovered this in 13 year of use....

Thank you for the hint!

So I understand the usefulness of the HIST key, but not of the partial hist. functions of the UP key (even if it seems natural to "browse" the history with the arrows).
