[Gimp-docs] clarification needed

[Marco Ciampa <ciampix posteo net>]

Hi people,
GIMP, tool option dialog.

The button on the bottom right "Reset to default values SHIFT Reset all
tool options" ... Is there someone who can explain to me the function of
pressing of the Shift key during the press of those button?
What is the difference between with and without pressing SHIFT?

TIA
