LXDE桌面系统设置快捷键

一、说明

        LXDE利用openbox来实现快捷键。但是LXDE还没有提供快捷键的图形管理前端。需要手动修改其对应的xml配置文件。配置文件目录在：用户文件夹/.config/openbox里，不同的系统文件名可能并不总是一样的，例如：

/root/.config/openbox/lubuntu-rc.xml

        可以在这里进行相关快捷键的修改。内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!-- Do not edit this file, it will be overwritten on install.
        Copy the file to $HOME/.config/openbox/ instead. -->
<openbox_config xmlns="http://openbox.org/3.4/rc" xmlns:xi="http://www.w3.org/2001/XInclude">

       apply -->
    <followMouse>no</followMouse>
    <!-- move focus to a window when you move the mouse into it -->
    <focusLast>yes</focusLast>
    <!-- focus the last used window when changing desktops, instead of the one
       under the mouse pointer. when followMouse is enabled -->
    <underMouse>no</underMouse>
    <!-- move focus under the mouse, even when the mouse is not moving -->
    <focusDelay>200</focusDelay>
    <!-- when followMouse is enabled, the mouse must be inside the window for
       this many milliseconds (1000 = 1 sec) before moving focus to it -->
    <raiseOnFocus>no</raiseOnFocus>
    <!-- when followMouse is enabled, and a window is given focus by moving the
       mouse into it, also raise the window -->

    <!-- The monitor where Openbox should place popup dialogs such as the
