It maintains a stack of clips you have Ctrl-C'ed out of a variety of applications. It considers the stack to grow down. To PowerPaste you can tell it to paste is the the up direction, pasting the newest, then next newest etc. clip on the stack, in reverse order to the way you collected the clips,u each time you hit Ctrl-V . Or you can point to an old clip in the stack and tell it to PowerPaste down, and it will paste the old clip, then the next newer etc, in the same order you collected the clips, each time you hit Ctrl-V . It does many other things, but this is the bread and butter.
