\title{Map Manufacturer Identifiers to Open Reading Frame (ORF) Identifiers} 
  @ANNOBJPREFIX@ORF is an R object that provides mappings between
  manufacturer and ORF identifiers.
  Each manufacturer identifier is mapped to a vector of ORF identifiers. The length of
  the vector may be one or longer, depending on how many ORF identifiers the
  manufacturer identifier can be mapped to. An \code{NA} is reported for any
  manufacturer identifier that cannot be mapped to an ORF identifier at this time.
  Annotation based on data provided by: @ORFSOURCE@

## select() interface:
## Objects in this package can be accessed using the select() interface
## from the AnnotationDbi package. See ?select for details.

## Bimap interface:
# Get the probe identifiers that are mapped to ORF identifiers
mapped_probes <- mappedkeys(x)
# Convert to a list
xx <- as.list(x[mapped_probes])
if(length(xx) > 0) {
  # Get the ORF identifiers for the first five probes
  # For the first probe
