One thing that I always liked in Windows and missed on the Macintosh was the ability to move files by cutting and pasting them. I think this is a pretty common complaint for Windows users switching to the Mac. I actually bought a product, TotalFinder, in most part, because it offers an easy cut and paste option in the Finder. It also has some other nice features such as tabbed Finder windows which is nice but, honestly, I mainly purchased it for the cut and paste.
Little did I know, Lion adds this function. Copy your file as normal. Then, instead of simply pasting the item with Command-V, also hold down Option. You’ll see the option for Paste change from “Paste” to “Move Item Here.” Viola! Cut and paste in the Finder.
