My laptop's got a mysterious extra button on it that doesn't cause any keyboard messages -- I've verified this with a low-level keyboard hook.
It appears that it's an "ACPI Fixed Feature Button". Any ideas how I'd go about responding when it's pressed? I found some discussion of how it works in kernel mode. Does this information percolate up to user mode? Or do I have to write a filter driver?
Win32 or .NET solutions accepted. Windows Vista.
