You can create Smart Groups which let you see macros matching certain criteria by clicking the ⊕ button at the bottom of the Groups column, and you can edit a smart group selecting it in the Groups list and clicking the Edit button, or by double clicking the Smart Group.

A Smart Group consists of a set of Search Strings, and any macro that matches any of the search strings will be listed in the Smart Group.

You can control or right click on a smart group to Rename or Duplicate it.
