I'm assembling a list of specific "grammar hints" in
http://mKRmKE.org/help/hint.mkr.
These hints show the MKR syntax for particular features, e.g.
pplist
iteration
production
array
For the present, you can browse the hints for the feature you want to use.
In the future, I plan to display these hints automatically when you make
a mistake using a particular feature.
