               FutureOS ROM M to support M4 SD card mass storage
               =================================================

Short description: The FutureOS ROM M provides support for the SD card of the
------------------ M4 expansion. Applications can be started and files can be
renamed, erased, copied, moved, typed, untagged or retagged. File-Headers can
be shown. New Sub-DIRectories can be created. Two (Sub-)DIRectories of the M4
SD card or any other media (A-L) can be accessed at the same time.

Usage: You can use Cursor keys + Copy + Enter + ESC. Or use the joystick with
------ both fire buttone (Fire 1 = Copy / Fire 2 = little Enter). In addition
you can use any connected mouse. Furthermore you can use 'Hotkeys' too.

Start Up: In the Desktop of FutureOS you can click at the mass storage icon or
--------- you can press the hotkey 'H' to enter the M4 Shell.
Now you can move left or right to select a function. The icon bar allows you
to Run, Type, Copy, Move, Erase and Rename files. Selection of a device icon
will read the corresponding DIRectory of the selected medium. Arrow keys allow
to select a medium for the left or right window.
Press 'little Enter', Fire 2 or arrow down to enter the file selection mode.
Press 'little Enter' or Fire 2 a second time to jump to the other file window.
And press it a third time to go back to the upper icon bar. Or press ESC once!
You can tag or untag files with Fire 1 or Copy.

Leave the M4 shell: Pressing ESC while operating in the icon bar will quit the
------------------- shell and bring you back to the OS Desktop.
In case you left by accident just press 'H' again to return to the M4 shell.

RUN an application: The first tagged file will executed. If this file has no
------------------- file header, then an error will be shown. Hotkey 'X'.

TYPE files: Here you can either type file(s) on screen (or show a screen).
----------- Or you can display file headers. Hotkeys 'T' and 'V'.

Copy files: In the middle of the icon bar there are two grey arrow symbols.
----------- Use them to copy or move all tagged file to the left or the right
target window. File names (and the target device) can be edited for each file
if selected. 
BEWARE: You must NOT move a file to itself, because this will DELETE it!

Erase files: All tagged files will be erased, but you will be asked if you are
------------ sure to delete the file or not. Hotkey 'E'.

Rename files (Create new Sub-DIRectory): Tagged Files can be renamed. And new
---------------------------------------- Sub-DIRectories can be created in the
actual M4 SD card directories. You'll be asked if you want to create the new
Sub-DIRectory in the current directory of the left or right window. This equals
SD-card medium 'N' (left window) or 'O' (right window). Hotkeys 'N' and 'M'

Retag or Untag files: Use hotkeys 'A' or 'U' like under the regular OS Desktop.
---------------------

Read DIRectories: Press hotkey 'D' anytime like under the regular OS Desktop.
-----------------

Move one DIRectory Level Up:
----------------------------
This can be done using the 'DEL' key when using a M4 directory (media N or O)
and using the left or write file window.
