An apparatus is configured to detect one or more particular user inputs from respective one or more positions, each position associated with a respective edge region of a display; and upon detection of the one or more particular user inputs, modify at least a portion of a foreground view on the display to create a peep-hole within the foreground view in the portion, the foreground view comprising first content data associated with a foreground application and the peep-hole comprising second content data. In this way, the peep-hole may be considered to replace parts of the foreground view with second content data. Corresponding methods and computer programs are also described.
