One more question regarding fonts on the Prime...

The default font is quite large - OK for the stack, but too big for the menus. I have successfully set the menus to Font10A (which is much smaller than the default font size), but setting the stack to this font makes it too small to be usable. Once the default fonts are changed, is there no way to get back to the default font without a reset? The documentation shows Font10A as the largest - but there must be a larger one internally stored that is bigger and used as the default. Does that font have a name that can be used with the ->FNT commands?
