If you've ever copied a folder's worth of files in Windows, you've come across the Confirm File Replace dialog, which asks you if you want to replace an existing file with a new file. You have the option to answer Yes just for this file, Yes to All—which will just replace all the originals with the new copies—or you can say No; what's missing is a button to say No to All. Rather than clicking No countless times if No to All is what you really want, tech weblog Online Tech Tips points out that Windows simulates the No to All response if you hold the Shift key and then click No. It's a strange feature, and actually one that we covered years ago, but it's worth a second mention. Vista changed this dialog entirely, but if you're still living la vida XP, it's a good shortcut to know.
