Non-limiting examples of the present disclosure describe functionality for content selection that efficiently enables block copying of content from an executing application even when content is traditionally non-selectable in the executing application. An application may be executing, for example, on a computing device. Input may be received that triggers activation of a user interface for content selection. A layered view of the application and the user interface may be presented based on the received input. As an example, the layered view presents the user interface layered over the application. A block portion of content from the application may be selected based on a single action. Among other examples, the single action may be a non-continuous device click or a non-continuous touch input processed through the user interface. Additional action(s) for the selected block portion of content may be accessible through the user interface.
