can I filter lines with a list of alternative OR strings?

Thanks, Dick! I’ll play with that and see how I get on. The filter is in a loop which mostly uses simple strings, so presumably I would need to separate any regex filters into a separate loop using 'with regex'.
I have also learned that this is called “alternation”. Didn’t know that, so now I can investigate further!
