(Feature Request?) Finding macros that use a variable

Continuing the discussion from Finding unused variables:
I would love to have a feature or macro that lists all macros that use a particular variable. This has uses by itself, but would also cooperate nicely with deleting specified variables.

This feature is already available:

  1. Click on the "All Macros" group
  2. Enter the Variable name in the Search box

Sort of. The search includes macros whose names match.
