I have some text in my paste buffer, e.g. I did a yw (yank word) and now I have 'foo' in my buffer. I now go to the word 'bar', and I want to replace it with my paste buffer. To replace the text manually I could do cw and then type the new word. How can I do a 'change word', but use the contents of my paste buffer instead of manually typing out the replacement word? The best option I have right no
