Math Virtual Keyboard Specifications - Version 2

This is a updated to the math virtual keyboard specifications.

Layout

When testing the keyboard I notice that is painful go to Symbol Layout to insert $ that marks the start and end of (La)TeX math environments. To solve this I add another key to the keyboard.
