Re: F and G ... and H (shifted function keys) Message #3 Posted by Andrés C. Rodríguez (Argentina) on 7 Aug 2003, 8:05 a.m., in response to message #2 by Gordon Dyer
Just a comment: "h" first appeared in the HP 67, long before the HP 34.
While "f(x)" and "g(x)" are usual mathematical function notation (as is "f1(x)"); the letter selection also fit nicely with the A,B,C,D,E definable keys on the HP 65 and 67. This may have been infuenced by the physical layout of the handhelds (5 top row keys).
The need for a sixth top row key, as in the Pioneers, with A...F meaning, is very convenient for hexadecimal functions; but this doesn't seems to have been an important concern before 1980. If "F" means binary 1111 or decimal 15, then the function key should be labeled differently.
The angled "left shift" and "right shift" keys are compatible with this. Personally, I don´t like them, but one must concede that such arrows are a blessing for persons with color blindness.
