I follow your point here, but if you took this logic to the extreme, no shift need be shown at all since LOOP and TEST are unique. But time and experience have shown that most people expect, and as a result many (not all) people documenting programs show keystrokes using the [f] or [g] to provide an unambiguous hint that the user should be looking at the labels printed on the bezel, typically above the key, sometimes on the front face of the key, and totally oddly, below the key on the 67.H2X wrote: ↑Tue Jun 25, 2019 4:33 pmInteresting! But maybe only [SHIFT] is really needed, as long as yellow and blue label names never clash - which they don't?
Consider [SHIFT]+[LOOP] and [SHIFT]+[TEST] as but one example. You'd still need to locate which button the [LOOP] and [TEST] labels are on, regardless of how you refer to the fact they are shifted.
And the color-blindness point before Didier made is the best point of all, so it seems we're back to the starting place, which should be no surprise; Walter has been doing this for quite a long time.
