Not in Current Product Plan

The enter key selects a particular feature (seemingly randomly) instead of returning the whole list of all possible results, like the magnifying/search button does.
The enter key should behave in the same way that the magnifying glass/search button does.
When searching against a feature layer, the search box will display a list of potential matches. Clicking an item from the list will select that feature. By default the top item is selected, so hitting the enter key selects the top feature.
This behavior is as designed and modifying it is not in the product plan as it would cause confusion with the returned list of features that are nearby the search term.
