This may not be ideal, but please try this:
Select "NRST" then "Modify Search", then type the Fix ID into the search box. This will center the map on the fix. Currently Fixes are not graphically shown on the map.

Jim,
An auto-populating list feature is on out Wish-List. Essentially as you start typing it would begin building closest matches to your text in a scrollable pane. Stay tuned on this, it's a bit of a UI modification to accommodate the building list and some database prep. For now make sure you have Text Search selected and it will try to find a list of what's close.
