[TxMt] Language grammar question - how does newline get inserted when you type "{\r}" ?

[John Clayton]

  Thanks, Alan, that's sweet, I had actually started from the one in  
the Io project source. There are a few changes that I could add back  
from what I was working on (like adding 'then', 'else', ''elseif' to  
keyword.control.io) if you'd be interested.

Now, fire up the moon.

John
