SED - Working with Multivalued Data
When in a normal data window, some edit functions normally associated with file handling actions have special usage and allow entry to and exit from value edit mode.
Value edit mode takes the contents of a multivalued field and displays each value as a separate line in much the same way as the EV command of the ED line editor. While value edit mode is active, the original parent buffer becomes read only.
Used with a dictionary I-type entry, this mode breaks compound I-types into separate lines to simplify editing.
Up to parent (Ctrl-X U)
Used in a value edit buffer, this function returns to the parent buffer, saving any changes into the main buffer.
Dive (Ctrl-X Ctrl-D)
When not positioned on a $INCLUDE statement, this function enters edit value mode.
Delete buffer (Ctrl-X K)
When in a value edit buffer, this function returns to the parent buffer, discarding any changes.
