Automatically indent while typing [message #1440700]

In my Xtext DSL editor I want to provide the following: Whenever I type a line that contains the keyword "connections," I want the editor to automatically increase the indentation of the next line. I got his working for parentheses, etc using the autoedit stuff in Xtext, but I couldn't figure out how to tie the indentation to a keyword. Is there an example available somewhere?

I've looked at DefaultAutoEditStrategyProvider and related classes, but without better documentation it is rather difficult to figure out what's supported and how to do use it.

OK, so I figured out how to make it work. In my AutoEditStrategyProvider's configure method I added

acceptor.accept(compoundMultiLineTerminals.newInstanceFor("connections", ";"), IDocument.DEFAULT_CONTENT_TYPE);

This works, but I am stumped as to why. In particular, depending on the string that I pass as the second parameter to newInstanceFor it (a) works as expected, (b) indents but also inserts the second string, or (c) does not indent the next line.
