narrowTo

Selects the next most narrow selection that contains all of a given unit type.

For example with text "fooBar" and a selection of "fooBa", narrowTo would shrink the selection to "foo" when the unit was "subword". This is because the two subwords in this selection are "foo" and "Bar".

Arguments
