I had good results with CopyPaste, a program which creates multiple clipboards you can store things in on a semipermanent basis. ctrl-shift-v-2 could be the command to paste the second stored clipboard, for instance (depending on your settings—it was very configurable). That only works for things that allow the use of the edit menu—not palette hotkey selections—but it could be a help.
