The easiest way to close a file, without exiting vEdit, is to double click the window’s icon; this is the same as selecting WINDOW > Close (Ctrl-F4). If this is the only window displaying the file, which is the typical case, it closes the file and the corresponding buffer.
If a file is displayed in two or more windows, WINDOW > Close does not close the file until you close its last window.
Alternatively, you can select FILE > Close ( Ctrl-W ) to close the current buffer, saving or abandoning any file in it. It also closes all windows attached to the buffer. In the typical case where each file is displayed in only one window, FILE > Close and WINDOW > Close are identical.
