// SecureCRT 如果没有配置好，这个就很管用了。 

其他特定的键绑定:

Here "2T" means Press TAB twice
$ 2T - All available commands(common) //命令行补全，我认为是 Bash 最好用的一点 
$ (string)2T - All available commands starting with (string)
$ /2T - Entire directory structure including Hidden one 
$ ./2T - Only Sub Dirs inside including Hidden one
$ *2T - Only Sub Dirs inside without Hidden one
$ ~2T - All Present Users on system from "/etc/passwd" //第一次见到，很好用
$ $2T - All Sys variables //写Shell脚本的时候很实用 
$ @2T - Entries from "/etc/hosts"  //第一次见到
$ =2T - Output like ls or dir //好像还不如 ls 快捷
补充:
Esc + T - 交换光标前面的两个单词

很多来自GNU 的 readline 库。另外一份总结也很好

记忆是所有技术人员的敌人。一次要把所有的都记住是不可能的。针对自己的使用习惯，对少数快捷键反复使用，短期内就会有效果。

你还知道那些好用的快捷键 ? 补充一下 ?
