1.记事本录入以下文字：

/*  * 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！！  *  * This program is free software; you can redistribute it and/or modify  * it under the terms of the GNU General Public License as published by  * the Free Software Foundation; either version 2 of the License, or  * (at your option) any later version.  *  * This program is distributed in the hope that it will be useful,  * but WITHOUT ANY WARRANTY; without even the implied warranty of  * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

2.保存为uperBackspace.em按说明进行操作

3.欣赏效果

PS:改变comment字体，可以使中文紧凑显示.
