All of the keyboards are designed so that phantoms will not happen during normal typing,
only when unusual key combinations like the one just described are pressed. Normally,
the keyboard will appear to have "N-key rollover," which means that you will run out of
fingers before generating a ghost character.
NOTE
Seven keys are not part of the matrix, and will never contribute to generating phantoms.
These keys are: CIRL, the two SHIFT keys, the two Amiga keys, and the two ALT keys.
