Multimedia keyboards, i.e. keyboards with additional function keys are not uncommon nowadays. However, without special software, these additional keys will not work. That's what programs like MKey are for. MKey is primarily used to work with additional keys, but it can also be used to register key combinations on a regular keyboard. That is, you can assign keyboard shortcuts using the Ctrl, Shift, Win and Alt keys. MKey is a worthy substitute for the standard programs that come with keyboards.
