Open all selected items at same time when hit Enter key

WORKS WITH CONTEXT MENU
-Select multiple search result items
-Right click to show context menu
-Select “Open with Default Applications”
This opens up all the selected items at the same time

DOES NOT WORK WITH ENTER KEY
-Select multiple search result items
-Hit your Enter key
This only opens up one of the selected items instead of all of them. If possible would think this should match how the context menu method above performs.

Thank You
