allows you to copy text that you\'re replacing when pasting. For example, if you have text copied in your clipboard, select different text and paste over it, replacing the selected text. Then automatically, the text that you replaced gets copied to your clipboard so that you can then paste it elsewhere.
After installing, using the keyboard shortcut Cmd+Opt+V to paste in the clipboard while copying the text it's replacing.
This is very useful if you want to swap locations of text, as it doesn\'t make you paste the text you originally wanted to replace somewhere else before replacing it.
