UI: the Quick Apply shortcut doesn't also run its first entry

Cmd+Return opened Quick Apply, and in the same frame the list saw the
same press as Enter and ran its first entry (New Document). A key press
that fires a command shortcut is now consumed, so nothing else handles
it that frame. This also stops Cmd+Return from inserting a paragraph
break while typing.
