first of all, you can find almost everything on this git page: https://github.com/SublimeText/CTags
I'm just doing some translation work here, and of course, trying to make a note.
notes that I've try it out couple times both on my laptop in office and @ home.
install CTAGS:
0.在Package Control：Install 中找到Ctags，安装。
1.网上找到后，下载ctags58.zip包，解压，把ctags.exe放在sublime 2 的目录里[ probably u can put it wherever u like]，配置path。
1.1 执行一个 ctags -R -f .tags的命令 // it will run a couple minutes；
2. open a file of your project and run this command in st2 : ctrl t r ; let it build for another couple minutes.
2.2 choose a function where it's been invoked, type in : ctrl t t ; see what comes out // jump to the definition. It just doesnot work for param.
u can also 在st2中，打开default设置查看各种快捷键用法，貌似有很多用不了,conflict。
