Trash
The Trash is a desktop icon which is used to delete a file or directory. If you wish
to delete a file or empty directory, simply drag and drop that icon to the Trash. When
you release the trackball button, the icon will appear (as broken pieces) inside the
Trash. To physically erase the file or directory from the hard disk drive, select the
Trash command Empty the Trash. To retrieve a discarded file or directory, drag
it from the Trash back to its original location in the desktop.

system is contained on the rtVAX 300 board.
Window
When an icon is opened, it becomes a window. A window is a work area inside a
frame which appears when a program is started or a file/directory is opened.
Window Button Menu
At the leftmost top corner of every window is located a small "button". When the
trackball pointer is placed on this button, the Window Button Menu is displayed.
Window operations such as minimizing, moving, resizing, and closing are select-
able as menu items or keystrokes.
