Navigate the Open / Save Dialogs With the Keyboard

Opening or saving files can be so very tedious when your application doesn't start with the right default folder, but instead of clicking and clicking your mouse to get where you're going, you can simply use the keyboard to change the folder.
You can use ".." without the quotes to go up a folder, use shell:desktop to change to the desktop folder, or just start typing in the full path to a file.
