HP calculators: origin of prefix key labels f and g

I wonder about the motivation of the developers of HP to label the keys to prefix of RPN calculators in the 1970s and 80 by the letters f and g. obviously, the reason was not absolutely background as angles arrows were later invented instead. Compare: hp15c.org and Wikipedia/HP - 32S

Hello

I see you have some answers on MoHPC. I'll reference the thread here for someone down on this post.

origin of the prefix key f and g on MoHPC labels

Kind regards.

  • Checkbox labels disappear and colors modified during export to interactive PDF

    I did an InDesign document that contains two simple text boxes: one containing the word 'Yes' – the other containing the word 'no '. The background color of these two boxes are defined as 100% Cyan. After that, I have converted both of them boxes [(voir 1) in the illustration below].

    But when you export as interactive PDF, the background color of change boxes 17/11/0/0 and the 'yes' and ' no. "-labels are not visible in the exported PDF document [(voir 2) in the illustration below]."»

    However, when you click on the box in Acrobat, the box contains its original color 100% cyan and label and check mark appears [(voir 3) in the illustration below].

    But when I click on an empty space outside the box, the box label disappears again, and the background color changes again in 17, 11, 0, 0 [(voir 4) in the illustration below].

    My intention is that, when you view the document in Acrobat Reader, check boxes 100% Cyan with labels 'Yes' and 'No' obvious, when you click on one of them, the check box appears and background color remains 100% Cyan and the labels remain visible - also when you click off the beaten later.

    I'm doing something wrong, or is this a software problem?

    I appriciate all the tips and tricks on how to achieve my goal. Thanks in advance!

    Hello

    Looks like you need a new keyboard.

    You can order all the compatible parts of the ASP from Toshiba in your country.
    Also the keyboard.

    Service technicians could order the part directly from Toshiba.

    Usually, the replacement of keyboard is not very difficult but if you have no experience in these replacements ASP assistance would be required.
