STOP THE ICONS FROM MOVING

In the previous tip, I showed how you can drag a document onto an application's icon in the Dock. But sometimes you may be trying to add the document to a folder in the Dock. When you do this, the Dock thinks you're actually trying to add the document to the Dock itself, rather than dropping it on the folder, so it kindly slides the icons out of the way to make room for your document. That's incredibly polite (for an operating system anyway), but it can also be incredibly annoying if that's not what you're trying to do. If this happens to you, just hold the Command key as you drag and the icons will stay put, enabling you to drop the document into a "non-moving" object.
