The funny thing is that it’s usually all in the OS documentation. But who reads this stuff? Why do they even make “instructions” if nobody reads them ? ;) Well we don’t read them and sometimes we find out about some stuff either by accident or in some web article (this is what you’re doing right now, ha!). First of all let’s take the dock. The dock (in my case it’s a custom Onyx dock but it works just as your regular “shelf” in Leopard…) you have a bunch of icons and a couple of stacks probably like your Documents, your Downloads, some people (like me) also have their applications in a stack for easy access. The trick is :
Press Command, hold it and click on anything on the dock
That takes you to a finder window with the file selected. You can easily find where exactly is that app, that file dragged to the dock, or any element in stacks because if you open a stack and Command + click on an item in it it will open a finder window with that item highlited. Pretty cool huh ?
