source insight 中文间距大问题和backspace使用

我想大家都知道默认情况下，往Source Insight里输入中文，字间距相当的大，这篇文章将帮助你解决这个问题。具体设置如下：

1.Options->Style Properties
2. 在左边Style Name下找到Comment Multi Line和Comment.在其右边对应的Font属性框下的Font Name中选“Pick...” 设置为宋体、常规、小四。确定，退回Style Properties界面，Size设为10。最后设置Clolors框下Foreground，点“Pick...”选择一种自己喜欢的颜色就OK了。
3.Done

backspace重新定义：

1、后退键

新建一个文件，命名为SuperBackspace.em，将以下代码保存到该文件中，然后按照注释中的步骤进行安装。

/*
* 代替SourceInsight原有的Backspace功能（希望如此）
* 增加了对双字节汉字的支持，在删除汉字的时候也能同时删除汉字的高字节而缓解半个汉字问题
* 能够对光标在汉字中间的情况进行自动修正
*
* 安装：
* ① 复制入SourceInsight安装目录；
* ② Project→Open Project，打开Base项目；
* ③ 将复制过去的SuperBackspace.em添加入Base项目；
* ④ 重启SourceInsight；
* ⑤ Options→Key Assignments，将Marco: SuperBackspace绑定到BackSpace键；
* ⑥ Enjoy！！
