- -l Detailed driver information
- -n Hexadecimal display
- -f Display all information
- -1 Display key combinations line by line
- -S Set output format (0: default, 1: full, 2: line by line, 3: simple)
- --funcs-only Function key information
- --keys-only Key combination information
- --compose-only Regular key information
Examples
