Is there a way to create shortcuts for folders in the Save dialog?

Drag a folder from the column-view into the sidebar.

To remove, drag from the sidebar, move over the column-view and a "cloud of destruction" will appear with the cursor; release and the item will be removed from the sidebar.

 

I think the OP is talking about adding a keyboard shortcut, as shown on the home folder, not how to remove a folder from the sidebar.

OP: That shortcut is used for "Go to Home" in Finder, Safari, etc. It's not a shortcut to go to any folder.
