From MORILLON Alain:
"MA keyboard" is a virtual keyboard that allows you to enter characters from a single click. The cyrillic, qwerty, azerty and mathematics keyboards are provided by default. You can create your own keyboard and add your shortcuts (Example: For a given key on your keyboard, you can type your full email address). "MA keyboard" will help you with applications requiring the striking of sometimes complicated sequences of characters (Example: Entering Unicode characters). "MA keyboard" can also be useful when your physical keyboard is far from where you sit and you have a wireless mouse at hand (for instance : launch a Google search from your sofa, a.s.o).
