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!
