Quick Ollydbg Question

I'm trying to move an entire function into a codecave. The function itself isn't particularly large but it's inefficient and prone to errors for me to simply copy by hand the code into the cave. I can copy the data to a clipboard, but can't seem to find a way to paste it into the cave.

Is there a better program to do this with? I also have IDA Pro.

you must copy the code into the clipboard,but only one line!
then doppelclickt the line in olly where you want to paste it.
Or make a rightclick and assemble.

ctrl + c = copy
ctrl + v = paste ;)
