ziggy: Those data are documented.
Each type of event that can happen has a short note in the help files that tells what fields it fills with what information. All other fields aren't used. This means that in the end, most fields are normally unused. Extra for example isn't used at all, this seems to be mainly for your self created events to attach objects.
Mods from what I can remember is only used on HotKeyEvent for the modifier_key constant.
ID, as you assume, is the constant for the EVENT, so EVENT_MOUSEDOWN or whatever.
There is no more information on that in the docs ... After all, I don't think more is needed, as something that has no usefull data does not need 10 lines to describe that it has no usefull data, does it? ^^
