New feature in iOS4 - text replace

If you thought cut, copy and paste was nice, this new feature of replacing text would certainly be a much welcomed addition. In the same way that you cut, copy and paste, tap on the text that you are interested in and release. The text would be highlighted and some options would appear to you. The familiar ones are of course cut and copy - the new one is replace.

Click on replace and select one of the recommended words to replace your current one and you are done! Simple!

Now that we have cut, copy, paste and replace, what do you think would be a nice new feature to add in the future?
