Just a shameless plug for the editors that I wrote -- intellisense works for the WITH with any part. This was one of my "gripes" with the VFP built in editor. Basically I parse the full definition to determine the allowed values. The only part that I did not implement is the use case of:

LOCAL loFormObject AS Form

WITH loFormObject
  .
ENDWITH

I don't use the AS clause in the code as it really doesn't enforce datatypes -- I would prefer that it did (strong data typing). So I have not made the effort to add this. I have thought about adding this but have not taken the time...
