I've looked at all the examples in the sticky thread and I still can't get my head around regular expressions!
Luckily most of my requirements have been met by what I've found on this forum.
One thing I cannot do is to make the first letter of the word immediately following an ellipsis character (3 dots) upper case.
For example '...first Word' should become '...First Word'.
Does anyone have an expression to do this, or a similar example which I can modify?

This is best done with case conversion:
Action: Case Conversion
Field: _ALL
Conversion: Mixed Case
Words begin from/after any of: {[(-_/".
(the last line does the trick)

That does it!
My case conversion action was missing the '.'
Thanks!
