The four checkboxes (RSD, HHold, HD, and TSD)
can be toggled by pressing the spacebar when the
checkbox is selected. The radio button for Mic
(choosing between API and APO for the ADC in-
put source) is changed by using the up or down ar-
row. The Reset Button (at the bottom of the main
window) can be pressed when selected by pressing
the spacebar, or at anytime by pressing the enter
key. As above, you can always use the mouse to se-
lect the value.
