Ok, end of statement is what I was looking for. Thanks.
I know that emacs can't possibly know what my intention is, but it
_can_ know what the appropriate end-of-statement character is for the
current context. All I'm looking for is a command that will insert
that character; I'll take care of making sure it's inserted at the
appropriate time myself.
To be more clear, I'm trying to replecate a behavior in TextMate. In
TextMate, if you hit command-shift-return it adds the context-
appropriate end-of-statement character to the end of the current line,
creates a new line below it, and indents that new line. I can already
make Emacs do everything other than insert the end-of-statement
character, but that's only because I don't know how to programatically
determine what the correct character is.
