Счас мода выпускать клавы с разными новыми клавишами. Но это к делу не относится. У меня ноутбук и у него две дополнительных кнопки. Windows к этим кнопкам назначил Interent Explorer и OutLock.
Вопрос как отловить нажатие этих клавиш и других кнопок тоже.
Если кто знает подскажите, желательно поподробнеееееееееееееееее...

По-моему, это что-то из VK_OEM_xxx.
