DISPLAY_FIND is an optional toggle field. The display find toggle will allow a find block to be displayed for a procedure step inside the procedure window. This toggle is best used when all other steps also have this toggle set and no procedure header is defined. Conversely, if there is a procedure header defined in IMFD, then using this toggle is only allowed for the 1st procedure step, and highly discouraged for subsequent steps, but allowed.
