No Zoom icon; can't make keyboard shortcut
Our organization has just upgraded from FM 9 to 13. Many changes. Among them, an inability now to use the Zoom command without going up to the View menu. There used to be a Zoom icon I could use, and now I don't see it anywhere. Worse, I now can't make a customized keyboard shortcut for some reason. I'm in Mac OS10.9 (Mavericks), and though I've specified custom Zoom In and Zoom Out shortcuts via Keyboard in System Preferences, it doesn't work. It isn't a general OS conflict, either. I used command-control-hyphen and plus sign for years. Now it isn't working.
Any help greatly appreciated.
