25 K / F/ DUE Keys in CFS

In the Display/Modify mode of CFS, pressing F1 has the same effect as K1, namely returning to the file list (equivalent to the LST command). In contrast to the K1 key, however, the last amendments made on the screen will not be lost; they will be written to the file.

After erroneously ending EDT (pressing the K1 key after the Action Code EDFn), pressing the F1 key will return the user to the last stage in EDT before the K1 key was pressed. This is only possible if no new file list has been selected.

In the Help System, the F1 key will display the next page of a Help menu.

In the Phantom Mode of the Restore process, the user can move the dialog by n steps forwards or backwards by first clearing the screen, then typing +n/-n/++/-- in the top left corner, and finally pressing the K1 key.
