Show ALL files including the ones that start with periods?

Hello.

Is there a way to show ALL and access files in updated Mac OS X (10.5.8 and 10.8.3)'s Finder without going to Terminal (ls -all)? The reason is why I need to recover older backup copies from Time Machine, but I cannot figure out how to tell their Finders to show these .filenames files in my home directories/folders.

Thank you in advance. 🙂
