How to do horizontal scroll in Numbers on a non-touch screen?
I just loaded an Excel spreadsheet into Numbers, and it came across pretty well. Unfortunately the sheet is bigger horizontally than my iMac's screen. There doesn't seem to be a horizontal scroll bar, nor can I find a mode which allows dragging using the mouse. I can reduce the size of the whole sheet until it fits the screen, but then it's too small to work with. I can't believe there's no way to do this, but I can't find anything in the Help pages for Numbers.
By the way I'm using a conventional 3-button mouse. Perhaps if I were using a trackpad I could make the scroll happen with multiple-finger gestures, but I can't really believe that a trackpad is compulsory.
Can anyone help?
