This addon enables laptop users without numpad to use their RCS, main, retro and hover engines, and to play orbiter without any extra external hardware.
A new custom command is added to Orbiter, which displays a virtual numpad on screen when activated. All buttons perform their normal function you'd expect when using the real numpad keys, and pressing CTRL for finer RCS thrust is supported.
The virtual numpad does *NOT* control the aerodynamic control surfaces, so most crafts won't be flyable in the atmosphere. This will not be fixed, as reentry and atmospheric flight is hard enough even with a physical numpad, so I'd really recommend getting an external numpad -or even better- a joystick for atmospheric flight.
