配置sunpinyin的热键,需要运行这个脚本
$ /usr/lib64/ibus-sunpinyin/ibus-setup-sunpinyin
python3下会出错：
$ /usr/lib64/ibus-sunpinyin/ibus-setup-sunpinyin File "/usr/share//ibus-sunpinyin/setup/main.py", line 427 mappings = [MappingInfo('togglebutton1', [('`',None), ('~',u'～')]), ^ SyntaxError: invalid syntax
如果系统默认为python3, 会返回上面的错误，需要切换到python2,
# eselect python list Available Python interpreters: [1] python2.7 [2] python3.2 * # eselect python set 1
