source Insight unknown command or macro 解决办法

0x00 前言

在接手一个新项目的时候由于别人的代码对于自己来说太过于陌生，因此使用一个代码组织良好的编辑器来看代码至关重要，毫无例外，SI是比较好的选择，但是老外的东西对中文支持就是不好。大多是情况下的中文乱码可以通过将原文件另存为编码格式为ANSI解决。但是今天碰到了使用backspace和左右移动光标时的问题（unknown command or macro：XXX）。

0x01 解决办法

1.在sourceinsight的安装目录下创建新以下文件：

序号	文件名
1	ShiftCursorLeft.em
2	ShiftCursorRight.em
3	SuperCursorLeft.em
4	SuperCursorRight.em
5	superbackspace.em
6	superdelete.em

每个文件的代码如下：

2.将这些文件复制到SI的base工程目录下（base工程在你的SI统一的工程目录下）。
3.用SI打开base工程，然后通过Project->Add and remove project files
添加刚刚复制过来的文件

然后添加Add all。
4.打开options->key assignments，在command中过滤出 macro开头的（宏）。

找到super开头的几个宏，分别绑定对应的按键。如superbackspace -> assign new key 然后按下 键盘退格键（backspace）。完成。

总结

上述方法将me分别进行创建，方便管理，但是也可以放入一个me文件中。道理都是一样的。
