elementary OS的桌面十分简单且易于使用。它包括两个部分：面板和 DOCK。你可以通过系统设置→桌面→壁纸来定义桌面的壁纸。
若要用键盘快捷键打开应用程序菜单，只需同时将 ⌘ + 空格 按下即可。
在面板右侧有一些图标，它们被称为“指示器”。这些指示器们可以告知阁下系统的即时状态（例如 网络连接、电池电量、音频输入输出、通知 之类）点选其中一个指示器可以获知更多延伸信息与相关可执行动作。
The contents of the dock are easily customizable. To add an app to the dock, drag and drop it from the Applications Menu or right-click an open app's icon and choose Keep in Dock. To remove an app from the dock, drag it off and drop it in an empty space on your desktop or right-click the icon and uncheck Keep in Dock. To rearrange apps on the dock, simply drag and drop them.
默认情况下，Dock 会在当应用程序最大化时从屏幕底部隐藏。仅需移动鼠标到屏幕的底部中间，即可重新显示 Dock。
您可以通过系统设置 → 桌面 → Dock自定义 Dock 设置。
When you open an app, its window appears on the desktop. Each app typically has three areas: the window buttons, a toolbar, and the contents of the app.
Many apps have a HeaderBar at the top of the app. This area contains common actions or navigation items for the app, plus the Window Buttons.
You can move an app's window around the desktop by dragging anywhere on the HeaderBar, including on buttons.
An app's Window Buttons are at the top corners of the app window. The close button is on the left and the maximize button is on the right. Pressing the close button will close the app's window. Pressing the maximize button will toggle whether the app window takes up the full screen or not.
elementary OS supports two types of multitasking: windows and workspaces.
Apps open in app windows. They can overlap on your desktop and be moved around. You can switch between windows several ways:
You can customize these shortcuts through System Settings → Keyboard → Shortcuts → Windows.
You can also configure "hot corners" (shortcuts activated by placing your cursor in the corner of the display) to activate multi-tasking functions like the window overview, workspace overview, and more.
You can customize hot corners through System Settings → Desktop → Hot Corners.
By default, all app windows open on one workspace. However, you can use multiple workspaces to organize your workflow:
You can customize these shortcuts through System Settings → Keyboard → Shortcuts → Workspaces.
Note: ⌘ refers to the "super" key. It is also known as the "Windows" key on most PCs or the "Command" key on Macs.
The panel, dock, and workspaces appear only on the primary display. Any other attached displays act as standalone workspaces. To manage and rearrange displays, head to System Settings → Displays. Your primary display is marked with a filled-in star () and each display's settings can be changed from its cog () menu.
elementary OS comes bundled with AppCenter, an app store for free apps. Installing a new app from AppCenter is easy:
You may be asked for your password prior to installing an app.
Note: Some software may not be available from AppCenter. While we don't recommend downloading software from the general Internet, apps that are compatible with Ubuntu 18.04 LTS should work on elementary OS Juno.
elementary OS includes updates as part of AppCenter. Notice the tab "Updates" at the top of the window. We recommend you check for updates at least once a week to make sure your computer has the latest features and protection.
For more information related to security patches, read the Ubuntu security notices.
elementary OS comes with a handy app called "System Settings" that controls all of your system-wide (or "global") preferences. System Settings gives you the ability to adjust things like keyboard shortcuts, display resolution, your wallpaper, and more.
You can quickly find settings you are looking for by typing keywords in the search bar at the top of the window. The contents of the System Settings window will filter down to match your search.
Keep in mind that System Settings only deals with the global preferences for elementary OS. Although some apps may also have their own preferences, you will not find them here. Instead, look for them inside the app in question.
