Thank you for your patient replay. Just get the idea about what you want.
What's your plan about when this api should be implemented?
I tried it on my Mac but it did not work. This new feature is compatible for Windows?
@Frulko Sorry for this delayed reply. This new feature is still in developing... You can check the status here:nwjs/nw.js#200

You can name
Hotkey.Ctrlto1,Hotkey.Shiftto1 << 1, etc. They don't need to be real key codes, and real key codes are not xor-able, you should convert them to key codes yourself. And mature GUI libraries such as Cocoa and Qt don't use key codes for modifier keys. The most important reason for this is to follow the custom of other GUI libraries.And there are other special keys like various media keys, you can predefine them in js and then convert them to real key codes in C++, like:
Use negative numbers here because chars' code are always positive, so you can easily distinguish them and then do the conversion.
Though global hot keys are different with accelerators, they're using the same key codes, so we should share code on this part between them, that's why I think we should separate the representation of a hot key with the actual registering of global hot keys.
