Snap-To

Snap-To is a Control Panel that snaps the cursor to the default button whenever a dialog comes up on your screen. Fairly simple, but it'll increase your speed when using a Macintosh, especially if you use dialogs often and/or have a large screen.

Snap-To can also do some other neat things, like snap the cursor back to its original location after you close a dialog box, or automatically disable itself in Open or Save dialogs. It can also "glide" the cursor to the default button instead of abruptly snapping it there.
