Try to open PresButan (MacOS will not let you because it doesn't come from an "identified developer). On Windows PC the Delete Key is often labelled as the Del key. Fn-Delete is a forward delete (as opposed to a backspace) and Fn-Delete is equivalent to the Delete Key on Windows PCs. More accurately, it doesnt have a key with the Windows symbol on it, but the one marked command or cmd acts as one. When Investor/RT documentation says to press the Delete Key, you have to hold down the Function key (Fn Key) on the Mac keyboard and press Delete. Download PresButan, a third-party app that makes the Delete key work in finder. The first and most obvious is that a Mac keyboard doesnt have a Windows key. Thankfully, there is a simple, many-stepped solution for this extremely minor inconvenience.
It would be nice, I thought, if the DELETE key performed the function printed on the key, which is defined as "removing (data) from a computer's memory"-as it does on Windows and other operating systems. But many Mac users have asked how to enable one-button deleting in Finder, and few answers are forthcoming. Sure, you can press "command+delete" to do this, which is admittedly not that tough.
