| Option | Description |
|---|---|
| Show tree indent guides | Display vertical lines that mark indent levels in tree views, for example, in the Project tool window. These lines can help you better understand the hierarchy of the components in your project. |
| Use smaller indents in trees | Decrease the amount of space between the tool window border and the text in tree views, for example, in the Project tool window. |
| Enable mnemonics in menus | Underline hotkeys that you can press to execute a menu action |
| Enable mnemonics in controls | Underline hotkeys that you can press to use controls in dialogs |
| Smooth scrolling | Scroll the UI smoothly, pixel-by-pixel, instead of line-by-line. This also enables animated smooth scrolling for Windows and Linux by default. You can disable it to use precise scrolling instead: press Ctrl+Shift+A, find and open the Smooth Scroll Options dialog, and disable the Animated smooth scrolling checkbox.  In this dialog, you can also set the duration of the scroll animation and change the appearance of the animation based on https://cubic-bezier.com/#.17,.67,.83,.67. |
| Drag-n-Drop with Alt pressed only | Avoid accidentally moving files, editor tabs, tool window buttons, and other UI components. When enabled, hold the Alt key to move things around. By default, this option is disabled and you can move everything without any extra keys. |
| Always show full path in window header | Show the full path to the project and to the current file in the main window header. When disabled, the header will show only the name of the project and file. |
| Display icons in menu items | Show icons to the left of the items in the main menu and context menus. |
| Background Image | Configure a custom background image for the IDE. |
