Orange-Shift extension

[Marco Polo]

I am using Plus42 since beta testing.

I find the single shift quite limiting in some activities, for example:

- quick update of a stored variable without using "STO" key (see HP48/50)

- quick conversion between UOMs without using the workaround of adding 0_newUOM (by the way, it does not work properly in °F<->°C conversion)

It would be possible to investigate the possibility to implement, limited to the top key row not to impact HP42 user paradigm, something like key longpress or shift-hold?

Thank you
