This will return the control to softkey level 4. The next block
generated will have the necessary G--code(s) to change the mode
inserted at the beginning of the block.
Important: This does not change the current operating mode of the
control. The control only inserts the blocks to change the operating mode
in the program. The mode does not change unless that block is executed or
some other MDI or program block that changes modes is executed.
