As a game programmer, I admit that I hate to touch my mouse when I'm writing my programs. When it comes to the Finder, I have to use mouse or trackpad to move or copy or open file with a strange extension with my favourite text editor. To be honest, I hate it very much. As a UNIX user, normally I heavily use Terminal.app to do this. But recently, I found a cool free program called Spark. This little thing really sparks my Finder (and other applications) by adding shortcut keys to everything. And for moving and copying files, I use Spark with AppleScript -- one for moving, and another for copying.
Just register these to Spark and then in the Finder, select the items that you want to move or copy to, hit the shortcut key and choose your destination from the dialog. Confirm it, and your file will be moved or copied to the destination folder. Enjoy!
