Access modifier icons can also be displayed if the visibility keyword is omitted; otherwise, the member icon is displayed.

All these and other options can be specified within the Edit | Painting | Visibility Icons page of CodeRush Classic Options.
Clicking the visibility indicator icon displays a drop-down menu of valid access modifiers for the member.
