Swiss-Army Clipboard
Actually, the software calls itself the Clipboard Swiss-Knife but it amounts to the same thing
This nifty little clipboard extender runs all the time (unless you untick the ‘run at startup’ option) and at its simplest pushes every copy or cut action you do onto a stack. The most recent can be pasted with Ctrl-1, the previous with Ctrl-2 down to Ctrl-0.
So, if you receive an email containing, say, 4 items of text that you want to paste into PediTree, instead of nipping back and forth between windows, you can copy all 4 and then recall them after a single window switch. Of course there is a trick to remembering which order you copied them in and hence which Ctrl-digit key they will be assigned to!

There is much more to it than I have outlined above. As well as the default ten Ctrl- pastes, you can preload 26 lettered projects, each of 10 items, so you might load up a set of family surnames or placenames so that you can paste rather than repeatedly typing them. This is all done by overloading combinations of the Ctrl and Win keys and is not too tricky to get used to.
