Keyboard support for the calculator plugin

Hi,

I know it's been asked several times ago, but i want to know if you plan to add the keyboard support for the calculator plugin. I think it's not a "nice to have" feature, but a "must have" feature.

Regards.

This is an old post but as a new user I would like to renew it. Keyboard/number pad input for the calculator plugin would sure be nice.
Thanks
