    • Click icons toolwindows toolWindowRun svg icon in the left gutter, and then choose icons actions startDebugger svg.

    • Click icons actions startDebugger svg on the toolbar.

    • On the main menu, go to Run | Debug 'selected configuration'.

    • Press Shift+F9.

  • Invoke the Run Anything dialog by pressing Double Ctrl (or search for Run anything in Help | Find ActionCtrl+Shift+A).
