Copy files on Mac OS X using drag-and-drop

Mac Stickies (and easily saving content)

I just learned about Mac Stickies, and they're pretty cool. If you're in a Cocoa application (like Safari, TextMate, and others) you can select text and/or graphics, and then easily save the content to a sticky note on your Mac desktop. To save the content you can either (a) remember the [Command][Shift][Y] keystroke, or else (b) click the application menu item (i.e., the "Safari" menu item if you're using Safari), then Services, then Make New Sticky Note.

The picture below shows what a Mac sticky note looks like when it's created on the desktop.
