When you drag and hold a file on top of a folder, the folder opens automatically. You can do this through a series of nested folders until you get to the folder where you want to drop the file. Once you do that and release the mouse button, all of the windows close. When you hold down the control key while clicking the mouse button to select a file or folder, you get a menu of commands that fit the context. Applications that are Mac OS 8 savvy can support these contextual menus.
Developers can also extend an application's contextual menus by creating plug-ins.
For example, there are already plug-ins that extend the Finder's menus. Two new options work well for novice users. Simple Finder shortens the Finder menus to essential commands. View by Button turns icons in a window into large, single-click buttons. The Desktop now supports view options like other Finder windows do.
