Fixing slow key issues with the FACOM converter
- Required some small API changes, shouldn't affect any other Scan modules (addition of a parameter)
- Still have the latching annoyances for some of the modifiers
- Swapped Esc and Tilde for convenience
- Removed the old Esc key from the latch list (no one needs 13 latches anyways...)
- Added the control cluster mappings (Insert, Delete, Home, End, PgUp, PgDn)
- All other misc keys are currently un-assigned if a keycap legend doesn't map to anything known
(e.g. blank keys, 000 and 00 are mapped, but your OS probably doesn't know what they mean :P)
