Glad I keeping some marbles.

I feel what we need - and is part of the ACE contribution to AEGIS - is a central switch handler (control panel type thing) which reads switches and that any scanning program can use.  The control panel would deal with all the methods and filtering and pass scan select (and more) to the scanning programs.  This would eliminate the need for multiple set-ups and a lot of duplicate effort in reading switch inputs.

Yes that is exactly correct. AFAIK the foot switch was a USB HID - ie
same as joystick. So the point was that sometimes having events
ignored by the OS can be useful.

Windows doesn't treat joysticks as first class input devices that all
programs must support (like mouse and keyboard). The same with default
X. I'm not familiar enough with the X switch stuff that Willie
mentioned, but get the impression switch events become first class
events so applications including desktop may react. As I said  it was
an "aside".
