Detailed Description

The keyboard scan codes used by FPLBase, which correspond to the physical location of a certain key on the keyboard. This is ideal for layout-specific controls, regardless of the operating system's mapping of the keys.

For example, if a given key (a) is pressed, it will result in FPL_SCANCODE_A being generated, even if the a key is mapped to a different character – perhaps the German A-umlaut (ä). This would be perfect in the case of WASD (for secondary arrow-keys), where the location of those four keys is important, regardless of the keystoke they generate.

The values in this enumeration are based on the USB usage page standard: Universal Serial Bus HID Usage Tables
