The result is as shown below.

$2t-all available commands (common)//command line completion, I think it's Bash's best use.
$ (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 the system from "/etc/passwd"//first time seen, very useful
$ $2t-all Sys variables//very practical when writing shell scripts
$ @2t-entries from "/etc/hosts"//First time see
$ =2t-output like ls or dir//seems to be better than LS fast
