sublime如何设置鼠标选中后字体的颜色

text 3的默认主题黑色背景，鼠标选中后为灰色，对比不明显。如何改变鼠标选中后的字体颜色让显示效果更犀利。

• ①打开 sublime text3 的安装路径 找到 Color Scheme - Default.sublime-package 也就是颜色主题包。
  我的是在 D:\Program Files (x86)\Install Files\Sublime Text 3\Packages
  

• ②使用压缩软件打开这个颜色主题包，选择用记事本打开即可。
  

• ③查找selection 并替换颜色的RGB16进制值。
  

• ④修改完成后，关闭文件，确认保存修改即可。
  选择确认修改，注意这时一定要关闭sublime，否则会导致文件修改失败。
