#Span.DoNotSearchOnEnter	Existence	UIs in WPF and Turnkey will search on Enter because they have seek expressions; you can turn this off by defining this TV at the ViewModel level

The default behavior of a seeker ViewModel is that the search button (a column tagged as a seeker) starts the search when you press "Enter". If you don't want "Enter" to start the search, you can use #Span.DoNotSearchOnEnter to turn it off.
