As the subject says, I am wondering why on older HP calcs the shift keys are labelled f and g when the colour should be enough. And why f and g and not any other letters.
Thanks for enlightening me.

This is just a guess, but perhaps they originally used f as "function" (which makes sense). So, when another function key was needed, the next letter was used. Or perhaps it is because f(x) and g(x) are the two most common function names used.
As far as not just having the color, that is probably for the manual writers and tech support people. It is probably easier, and faster, to say "f 3" rather than "mandarin 3" Just some thoughts, -Ben

Arnaud -- I remember that this topic came up once before. Single letters offer convenient shorthand reference for the shift keys, instead of printing colored squares or printing "(yellow)". "f" and "g" (and "h") are accepted mathematical notation for functions, and the shift keys generally offer access to additional functions. These letters also do not conflict with capital-letters A-E made available as program labels. Models having only one shift key and (in some cases) also lower-case alphanumerics (41C*, most Pioneers) dispensed with the "f" notation. Is the 16C the only one with both an "f" shift key and "F" for hexadecimal 15 and program label? -- Karl

f as function makes sense, because the HP65 used a f-1 (inverse function) key.
An other reason may be that first programable machines had A to E function keys, and f, g, h are a logical extension. J-F

F is for Function. G then H were added later as the keyboard became more cluttered on the later models. |
