Interface
Demos Commander is a text mode application. The main interface consists of two panels which display the file system. It is used in a similar way to many other programs run in the Unix shell. Arrow keys control file selection, the insert key is used to select files (but no directories) and the Function Keys perform operations such as renaming, editing and copying files. Unlike many full screen programs that run in console, Demos Commander is not capable of resizing itself when the console changes resolution (for example, when an xterm window is resized) nor able to support any other console resolution than 80x24.
