# Icons and symbols

While working in CLion, you can see various icons all around the UI. For most of them, you can get a tooltip description by hovering over an icon, for example:

However, there are some icons in the following UI areas that may not have tooltips: [Structure View](file-structure.html), [Breadcrumbs](using-code-editor.html#breadcrumbs), or one of the [Hierarchy Views](analyzing-applications.html) (Call, Method, or Imports Hierarchy).

## Structure, Hierarchy, and Breadcrumbs Icons

Elements in Structure View, Call Hierarchy or Method Hierarchy can also have visibility indicators: private ![](https://resources.jetbrains.com/help/img/idea/2026.2/app.nodes.c_private.svg), protected ![](https://resources.jetbrains.com/help/img/idea/2026.2/app.nodes.c_protected.svg), or public ![](https://resources.jetbrains.com/help/img/idea/2026.2/app.nodes.c_public.svg).
