[plt-dev] IDE and completion

He wanted to have a key-binding/structured editing where you would
introduce a new form where the editor knew what the pieces would be.
So if you did Ctrl-Define (whatever) it would insert

(define _ _)

You would then tab to one of the _s.

We talked about also doing things like Ctrl-Map or Ctrl-ListProc and
tab through different list-ing options. We talked about having a key
binding for "Get an identifier in scope" (which it would then tab
through inside out) vs "Fresh expression"
