Tom,

Tune to the main frequency of the station you have in mind.  After a few 
seconds, the radio will acquire the HD signal if there is one.  Your XYL 
will be able to tell by the display, but you may hear a subtle change in the 
audio (usually a slight stutter) as the HD locks on.  If you're doing this 
on AM, the audio will become a lot sharper and clearer (unless there's 
static or noise, in which case you won't be able to acquire the HD). 
Getting back to FM, since that's the only place where you'll find stations 
with more than one HD subprogram, once the HD has been acquired, press the 
Up button (or tune clockwise one click if the radio has a tuning knob) to 
get to the HD2 subchannel, and continue the process to get to subsequent 
channels.  In most cases, HD2 is the limit, but you may find an occasional 
station with HD3.  If you go past the maximum number of channels, you'll 
hear the familiar white noise that happens between stations.

Steve
