The CFi Clipboard+ is operated via hotkeys, arrows, and Enter. And delete.
Also, a large number of context menu actions can be operated via hotkeys.
I used ArsClip many years ago, but was disappointed for some reason - maybe it was the number of issues I think it had with Unicode. I trust this or whatever it was has been fixed long ago, but could be why I didn't consider it when I moved to Vista.
The price is £20 once and for all (78 applications!) per PC.
I said it a little wrong, about delaying Start:
If I delay my CFi's start, my Explorer will crash, when CFi launches.
