Not seeing your book I cannot say for certain what you are querying.
The book is available from the Aikido Journal website, and the full description can be found here
I do not have the full book, just the free sample PDF. It's only a few pages, but it lists what the author calls "The Sixteen Keys"
, which is a list of 16 basic techniques. A footnote to that list states that he has used "the most common contemporary names of these techniques"
, and acknowledges that there may be naming variations.
Here is the download link
for the free sample.
