Title: Open search on key.enter on selection in single mode

Currently after focusing control by TAB, pressing ENTER do nothing.
But when control is focused by SHIFT+TAB, pressing ENTER opens search.
Its because TAB go to , and SHIFT+TAB goes to .
Events 'keydown' on both elements are different in ENTER processing.
