The perhaps only remaining concern might also be typographical, that these arrows don't seem to be easily represented in HTML (so that the community can contribute docs and examples), e,g, like HTML entities. The f and g do, of course.
... I just found the ↰ and ↱ HTML entities, seemingly even abbreviations for "left shift" and "right shift".
Please give an hexadecimal unicode character code - I can't find any character looking like HP's shift arrows there so far. Thanks in advance.
Something like this?

↰ is ↰ U+21B0 (↰) and ↱ is ↱ U+21B1 (↱).

Grazie, Massimo, and thanks ijabott!
Looking at the characters you mentioned, #x2BA2 and #x2BA3 are the best fitting ones in my view. And we have ,,, and in Luiz Vieira's Keyset font. Nevertheless I think the colours are matching the actual use on this keyboard better than direction arrows (see [EXIT] in particular). So I prefer [f] and [g] still.

The surface has changed a bit again:

There are three (3) locations still unoccupied so far. Any ideas for operations which shall go there?

I like the introduction of the angle function where it is now, i.e. next to the abs function, and the consequent shuffling makes sense.
I do not have suggestions for functions to occupy the available blanks.

Could we have an official picture of the entire updated keyboard?

%T might be nice (like the 12C), especially given it’s near
% &
Δ%.
The other thing I program as a user key on most calcs is log
y(x), but you may already have that on a key? Just an idea.

Log
x(y) is an unshifted function in
EXP.
%T returns - according to my information - 100 x/y. If this is true then it's a challenge for me to understand the use of this function. Why not just use x/y and do the trivial rest mentally? What do I miss?

You can use the answer in other calculations directly without having to add the 100 * yourself maybe.

%T preserves T, Z, and Y. This is the first thing I assign on the keyboard of any (non-finance) machine I start to use (except any 41C model, where PACK is the first thing I assign and %T is second). Also, one of the fundamental purposes of a calculator is to
not have to do the rest mentally.
I support assigning %T and honestly didn't notice until now it was not already available.
But perhaps its a good idea to leave a pair (both f- and g- shifts of a given key) of assignments blank to be used by each owner to assign his/her favorite function which is not assigned. In my case, I'll assign %T to one of them.
