In OS X 10.5, if you drag an file over an application icon and hit the space bar, the app will open for you. This makes drag-and-drop super easy. Here are a few screenshots to show how easy it is to use Leopard’s Spring Loaded Dock.
One of the things I always liked about XP/Vista was if you hovered over the taskbar, the program would open automatically. With Leopard, OS X adds this same functionality.
For example, if you want to drop a file from your desktop onto a program, just do the following. I’ll be dragging a file into cyberduck (ftp) as an example.
1. Click on the file and drag it over the the appropriate program.
2. When hovering over the application’s icon, hit the Space bar. Do not let go of the pressure held on the mouse/trackpad.
3. The app will open automatically while you still have a hold on the file. Drop the file into the open application.
