The number fields can be changed using the mouse wheel, up/down arrow keys, and clicking the up/down arrows (if your browser provides them). Use combinations of the Alt, Ctrl, and Shift keys to control which digit is changed. (All combinations work in Chrome, some don't work in other browsers.)

To see useful curves, the Min and Max wavelengths are different for solar radiation (about 6,000 K) and terrestrial radiation (about 300 K) - the buttons just make it easier to quickly get to the correct order of magnitude.
