Importing blizzard.j and commons.j and other to get keyboard events!

Can any one explain this?:

        else
            // Unrecognized key - ignore the request and return failure.
            return null

or this?:

WESTRING_UEVAL_UHOT=Hotkey

eval hotkey?

or this?

ESC Hotkey=512

that was from hotkey file...

1. Jass requires a return value outside of if/thens in case the condition is not fulfilled and nothing can be returned. That's why that is there.

2. It's just a string...

3. Used internally by the game engine. The index means nothing to us.

// Unrecognized key - ignore the request and return failure.

That's used in plenty of BJ functions. It's used if the user calls the function but doesn't supply a valid key. That way, you don't get ridiculous errors.
