An original command surface, such as a callout or pane, provides drill-in navigation functionality for reusing on-screen real estate when displaying a drilled-in command surface that presents additional commands or content related to a selected command button. Drill-in navigation can be effectuated by a command surface drill-in control having push and pop functionality that can be placed inside of various types of command surfaces. In response to execution of the command button, the push functionality pushes new content to a command surface stack that includes original content displayed by the original command surface. The drilled-in command surface displays the new content and a back button. In response to execution of the back button, the pop functionality removes the new content from the command surface stack causing the original content to be redisplayed by the original command surface.
