HP 15C CE key bounce

[Johnh]

There's definitely an issue in play here, with the hp15CE keys.

But I find there are ways to keep control. I find working under pressure and pressing keys with my fat thumbs is when I may occasionally get a double number, even though the click feels ok. Finger-tip pressing is more reliable. I think its because the pressing is concentrated on the key and doesn't spread onto the bezel or face plate. The issues occur with number entry, because this tend to be done fast to enter all the digits. Other keys get more deliberate attention to each press. Pressing each number twice at the start of a session helps too.

It shouldn't need such workarounds though. But its still my favourite calc.
