设置键盘布局

要改变键盘快捷键的设置：

单击菜单栏最右侧的图标，选择系统设置。
打开鼠标和触摸板，然后选择鼠标选项卡。
Select a category in the left pane, and the row for the desired action on the right. The current shortcut definition will change to New accelerator…
Hold down the desired key combination, or press Backspace to clear.

自定义快捷键

要设置您的自定义快捷键：

Select Custom Shortcuts in the left pane, and click the + button (or click the + button in any category). The Custom Shortcut window will appear.
Type a Name to identify the shortcut, and a Command to run an application, then click Apply. For example, if you wanted the shortcut to open Rhythmbox, you could name it Music and use the rhythmbox command.
Click Disabled in the row that was just added. When it changes to New accelerator…, hold down the desired shortcut key combination.

您设定的命令名称必须是有效的系统命令。您可以打开一个终端输入命令来查看其是否有效。一般来说用于打开程序的命令就是该程序的名字。

如果您想要改变快捷键对应的命令，双击快捷键的名字，然后在弹出的编辑快捷键窗口中编辑命令。
