How can I open a Terminal window directly from my current Finder location? I was wondering if there was any was I could right click inside any instance of a "Finder" window such that I have an option that says "Open Terminal Here". It would be really helpful.
As of Mac OS X Lion 10.7, Terminal provides Services for opening a new terminal window or tab at the selected folder in Finder. They also work with absolute pathnames selected in text (in any application). You can enable these services with System Preferences > Keyboard > Keyboard Shortcuts > Services. Look for "New Terminal at Folder" and "New Terminal Tab at Folder". You can also assign them shortcut keys.

In addition, you can now drag folders (and pathnames) onto the Terminal application icon to open a new terminal window, or onto a tab bar in a terminal window to create a new tab in that window. If you drag onto a tab (rather than into the terminal view) it will execute a complete cd command to switch to that directory without any additional typing.

As of OS X Mountain Lion 10.8, Command-Dragging into a terminal will also execute a complete cd command.

Note: The New Terminal at Folder service will become active when you select a folder in Finder. You cannot simply have the folder open and run the service "in place". Go back to the parent folder, select the relevant folder, then activate the service via the Services menu or context menu.
