There's a (free) program I've been using that will give you 10 clipboards instead of one, it comes in very handy if say you want to apply for 3 credit cards or make 10 orders from the apple store, instead of typing in the same information over and over you can type it into a text document, copy 10 fields onto separate clipboards using ctrl+1+c ctrl+2+c etc and then paste them the same way ctrl+v+1 ctrl+v+2 etc.http://www.paludour.net/TenClips.html
ctrl+c+1, ctrl+v+2 etc. sound like annoying key combinations IMHO.
Actually I believe it's ctrl+1, ctrl+2 etc to change clipboards. Regular ctrl+c, ctrl+v to copy/paste from the selected clipboard. At least that's what I gathered from the website.
That's better. These programs that always run in the background scare me though, they tend to hog resources.
Well if they're written well they wouldn't, but I agree a lot of them are pretty resource intensive.
