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

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.


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