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.
