Google Drive interface control panel allows swift navigation among folders. The interface comprises a search engine, to search a document or folder by name or part of the name, and provides various options to restrict the search by type or other criteria.
Basic browsing is achieved by means of small triangles to the left of folder names, in the browse area of the control panel. Clicking on a triangle pointing to the right displays the children folders (and directs the triangle downward); clicking on a triangle pointing downward hides the children folders (and directs the triangle to the right).
For more information on browsing, check Google Drive interface.
