If we want to change in the filter driver the keyboard codes we write scan codes. Before the scan code reached the User mode it is translated to virtual code vk. If we look at the vk table there are unassigned values e.g. 0x3A - 0x40.
Under user mode we can call MapVirtualKey(0x40, MAPVK_VK_TO_VSC) if we want to see the mapping.
Is there a way to activate this unassigned values from the kernel and what is the mapping?
Can this be done in the keyboard Layout definition Dll?
If anywhere, that is where it would be done
