Toggling the hold status of more than one field at a time

You can toggle between holding or “freeing” more than one field at a time by entering one of the following hold commands in the Cmd field of the Field Selection/Edit panel:

HH: Holds or “frees” a block of fields.
Enter HH twice: first in the Cmd column at the start of the block of fields you want to hold or “free”, and again at the end of the block. File Manager toggles the hold status of each field in the selected block.
Hn: Holds or “frees” n fields.
Enter Hn in the Cmd field of the first field you want to hold or “free”. File Manager toggles the hold status of each field, starting from the first selected field and continuing for n fields.
