Is there a keyboard shortcut to open your Downloads folder in Mac OS X?

Which download folder were you talking about exactly..? Im probably asking an incredibly stupid and obvious question but…

I think the Leopard downloads folder.

You can try make one with Spark. I use it for apps too. http://www.shadowlab.org/Software/spark.php
Works from 10.3 to 10.5 I think.

I use quicksilver to do the same thing.

Quicksilver rocks.

Quicksilver is probably the best app out there for creating commands that don’t exist (at least those that aren’t as easy to find like this one!).

Although not a built-in OS X method, you can use the excellent shareware app Default Folder to accomplish this and a whole lot more.

I created an opt-shift-d shortcut using Spark for this. Remember if you want to replace the desktop shortcut, then you must also disable if in the Pref pane or they will conflict.
