Interface navigation tools

Navigation tools for an interface (e.g., a graphical user interface) are disclosed. In one aspect, a first stack item (e.g., a first directory) that includes one or more stack elements (e.g., subdirectories) is presented in the interface. User input selecting one of the one or more stack elements causes a scaled version of the first stack item (e.g., a smaller visual representation of the directory) and a second stack item (e.g., a selected subdirectory) that corresponds to the selected stack element to be presented in the interface. Selecting the scaled version of the first stack item causes the first stack item to be presented (e.g., a larger visual representation of the directory) in the interface.
