@Walter:
Yes, I agree. The principle ... is the thing. From a guiding principle point of view (in the HP tradition at least) ... I am proposing that cleaner and leaner is the way to go. That means colour only.
Haven't mentioned anything on arrows. However, I suppose one could posit that they might be useful ... if they were to be employed as on the HP 35s. For example, refer to the shifted function label placements above each key of the WP-43S landscape layout below.

But again, even in this case as well (re guiding principles et al) I believe that arrows would be unnecessary redundant clutter. IMHO ...
What say you ... ?
Then I must admit I misunderstood your post: I thought you were showing the HP-35S as your example of good shift key design. If not, however, why did you show this calculator at all? This world is enigmatic ...
Anyway, I concur with Tom in this matter: The design of the HP-35S has quite space for improvement, (not only) shift-key-wise.
Regarding f, g, and h: you wrote:

Though the HP tradition is simply f, g, and h for calculators with more than one shift key. Pure colours would have done as well - correct - but they chose additional tagging. And I like it this way. YMMV
What think you? (Is this the Scottish way of phrasing a question?)
