If you’re like me and use your desktop for temporary files and working documents (before you save them somewhere that’s backed-up), getting to the Desktop in an Open/Save dialogue window is a frequent operation.
Fortunately there’s a shortcut key for that – Cmd+D. Very handy.
Just don’t use it in Finder! (It’ll delete the currently selected file/folder of course.)
Seems to be a bit of a conflict there?
