"speak selected text when the key is pressed" doesn't work in numbers
>>> When I actuate CTRL + ESC there's no voice but I get a system 'boink' after about a second or two. This problem is only in Numbers (3.5.3.)
>>> It's on both of my macs (a 2010 MBP and a 2012 iMac, both running 10. 10. 3)
>>> It persists when I've changed the shortcut (I don't think it's a shortcut clash)
>>> Speech works in the Command Line and in System Preferences in the bit where you get to change the voices.
>>> The shortcut does produce speech in other apps (just now, MS Excel, Pages & TextEdit).
>>> It's intermittent, though in a way that's hard to make any realistic sense of the problem. It's not intermittent in that it'll cycle between working and working every minute or so: It's intermittent in that it works some days and not others.
>>> The original Numbers files are usually (certainly today) in iCloud but the problem persists if I save to my local drive.
Any ideas please?
