Command "." like [TAB]?

I noticed that when I hit "." in tsch I get the same thing that pwd returns. And if I hit ".." it essentially "cd .."s.

Are those system command aliases like "ll" for "ls -la" that come out-of-the-box.

PS Where are those command aliases kept again? "~/.alias"? I've got default command shortcuts (like "ll", or "l", those are Ls) but no ~/.alias by default, so there must be somewhere in the system they're stored.

Thanks!
