This is a small time tip, not sure whether most of you know this already, still, I'll post it.

I noticed that if you have an Open/Save dialog box, you sometimes have to navigate to the desktop or your respective stack to get the file. Well, if you come across one of those, just drag the file from your stack or desktop and it will automatically navigate to the folder and highlight the file!

Same works for Save dialog boxes as well. That is, it will automatically navigate to the folder which contains the file you just dragged in.

Happy Mac-ing.
