Are there any LAD reference docs here or is it completely greenfield?

I did some searches on LAD HIG and you get some really off-topic results,
good read, just off topic.

If it is greenfield then any concept of semantics should be dropped and
leave the basic concept of what key/button pairs should cause a controller
to do.

The net effect of the change is up to the app, no?
