给SourceInsight添加 “select all”,“CommentBlock”,“UncommentBlock”  功能
步骤如下：

1)       使用覆盖默认 utils.em 的方法导入宏  下载这个宏文件.
l          打开 “source insight”
l          打开 base project (菜单 project->open project，可以看到base project)
l          打开 “utils.em” 文件 (在右边的窗口中）用刚刚下载的utils.em文件的内容替代它.

2)       启用宏
l          菜单 “Options” -> “Key assignment”
l          在列表框中找到下面的宏:
Macro: CommentBlock
Macro: SelectAll
Macro: UncommentBlock
l          给这些宏分配按键
eg. “Ctrl+A” for “Select All”,“Ctrl+F11” for “CommentBlock” and “Shift+Ctrl+F11” for “UncommentBlock”

3)       试试看吧.
Close the project and create a new file. Randomly enter something,press “Ctrl+A”,“Ctrl+F11”,“Ctrl+Shift+F11” to have a try.

By default,it will comment the block of lines with “//” at the beginning of each line,but if the file is a PERL file (.pl),it will use “#” instead.  And you can change it for different file types by modifying the macro definition file (utils.em).
