We have an unpleasant mix of a "command-oriented" UI, where you select a
command (instead of an object) and THEN the system prompts you, modally,
for the object to apply that command to -- we should be moving AWAY from
this, not toward --

mixed along with with our "object-oriented" UI, where you select the object
first, THEN the contextual command to apply to it (via button or menu or
hot-key).

For example, you can select the instVar name (text) and use "References to
it (N)" off the menu (or hot-key) to show all references to an instVar that
way.  It would be easy to add an additional menu entry for assignments only.

Best,
  Chris


Another option might be to offer a pop-up menu similar to the code
