Answer 1

The numerical values in nrser's answer make more sense when viewed in hexadecimal form:

0x000000 => "No modifier",
0x020000 => "Shift",
0x040000 => "Control",
0x080000 => "Option",
0x100000 => "Command",

The others are simply bit-wise-ORs of the above values, for example:

0x060000 => "Shift + Control",
0x180000 => "Command + Option",
