Place the caret at the highlighted piece of code and press AltEnter:

You can also hover over the highlighted element and apply a quick-fix from the inspection popup:

For some inspections, you can open a preview by pressing CtrlShift0I.

If you perform code analysis or execute a single inspection in a larger scope of source files, CLion displays the detected code issues in the Problems tool window. When you select a specific issue in this window, its report is shown in the right part of the window.
