Hi, I'm trying to tab between open programs or applications using command-tab however open windows aren't being tabbed, not sure if that makes a lot of sense but command-tab shows Firefox, Finder, Safari but the selected window isn't coming to the front of the open programs or applications. Can someone please advise where i'm going wrong?. Is there a key for correcting spelling mistakes, typographical errors etc similar to the del key for deleting characters that precede text as opposed to deleting text using the delete button (hope i'm explaining this correctly). Thank you. Kind Regards.
