In the function list of 128 (129 subtracting the duplicate entry for e^x), STO+, STO-, STO*, and STO/ are four entries, so those are already counted.

Some interesting functions:
The yellow shift key is considered a function.
The ALPHA key is considered a function, in addition to AON and AOFF.
The 'Append' character/feature is considered a function.
The back-arrow (in addition to CLx) is considered a function.
GTO. (line number) is considered a function
GTO.. (add end to current program and pack) is considered a function.
The ON key is considered a separate function from the ON and OFF commands. (So turning on the calculator is a function?)
The PGRM key is considered a function.
The R/S (Run/Stop) key is considered a function, in addition to the programmable "STOP" command.
The USER key is considered a function.

There is no 'indirect addressing' function in the list. It is possible that HP considered that a 'feature' instead of a function (as documented by Zaphod).

What I was interested in was an HP documented list showing over 130 functions. I think I agree with Thomas Okken, the marketing department was not diligent about what the definitive number of functions was. The number probably originated in a meeting where the design engineers were bringing the marketing team on board and someone threw out 'over 130 functions', and that lived on for a few years before someone actually fixed it.
