Check out this video tutorial by Philip Rothman of NYC Music Services, which shows you many of the powerful things you can do with the Inspector in Sibelius 7, which is the new and improved replacement for the Properties window in previous versions of Sibelius.
The Inspector is much more useful than the Properties window in previous versions: it’s context-sensitive, so it only shows you options that are relevant to the object or objects you have selected; it’s keyboard-accessible, meaning you can tab around the window and make changes to values using just the keyboard (unlike previous versions, in which editing properties relied entirely on the mouse); and it opens itself to the appropriate size and position only when you need it (and can be pinned to the score if you want it to stick around all the time).
Philip’s tutorial shows you a variety of the advanced edits that you can make to notes, bars, lines and text in your score using the Inspector. You may be surprised at the power contained within that little black box!
