Before the effort to code this is done, you need to test whether a locked CC actually does what your translators need. As I said, locking stuff in Word is easy but that doesn't mean it will round-trip to your translators and come back the way you want.

Assuming the CC or group is a valid method, the next problem is how does the macro determine what is grey. In some places it might be RGB(150, 150,150), in others it might be RGB(149,150,150) etc. The macro would have to be told exactly what RGB numbers it is looking for.

If the 'grey' text has been applied by something consistent eg a paragraph or character style then it would be a piece of cake to code.
