Apple Thoughts: Copy and Paste at the Same Time

"This is why I love Mac developers - they see a problem and come up with an innovative, cool solution. If you've ever tried to copy and paste multiple lines of text, you know what a pain it is."

If you want to swap lines of text, this is the tool for you. It allows you to copy text that you are replacing with other text, while you are replacing it, if that makes sense. I've come across this problem in the past, as recently as yesterday, where I had to copy the text I wanted to replace, paste it on another line so I didn't lose it, then paste over the original line with the new text. Whew. It is a free download available here, and works on Snow Leopard.
