A special functions stack saves the last 10 plotted functions. You may move inside this stack with the UP and DOWN arrow keys. This operation was done before to assist users with old 80-keys keyboards, but since all standard keyboards nowadays are enhanced, there is no need for this operation any more. Help text is now referred in a more efficient way. If you have a three button mouse, your middle button can be used to invoke the on-line help screens.
