How to use the HUD?

[Dave Hunt]

Hi,

Since I had a quiet day at home alone, I took the plunge and put the 
12.04 release, dated 07-April onto my trusty note-taker.  I'm trying to 
figure how the HUD works.  I hit 'alt', and type in a search key, for 
instance, "preferences", while focused on a Firefox window.  As it 
happens, I guess the best result was the preferences for FF, but, what 
if I wanted some other preferences?  After typing my key, I tried moving 
around with the arrow keys.  How am I supposed to navigate my search hits?


Cheers,


Dave
