.... I want fluid mnemonic context sensitive keyboard that does not strain the memory as much as overloaded fixed keyboard. And is out of the way when it is not needed.

The prototype works fine in Chrome, but not Firefox Seriously though, interesting idea. You want a keyboard customized to a particular context, not one invoked by extra keystrokes like shift or menu keys, right? To do that, I would think you'd need the format of an individual cell, column or row to convey the information about which keyboard to use. Currency format invokes a financial-oriented keyboard, text format an alphanumeric keyboard, scientific format a specialized keyboard, etc. Maybe colorize cells to indicate format?

Any thought on that, and reducing the user's burden so you're not just transferring shift-key effort to format-cell action?
