- Some media keys may require special handling or may not be remappable
- Function keys (F1-F15) can have default system behaviors that may need to be overridden
- Modifier keys (Command, Shift, Control, Option) can be combined with other keys
- The codes listed are for US keyboard layout; other layouts may vary
