When is a Word not a Word?

Thanks for the explanation, I guess it's the wording in the dictionary that is not really clear (at least to me).  I think your example of having white space within quotes brought home the intention behind it all.

You get the correct xyz results because you enclosed the string to search for in quotes.  My problem was because I was trying to find a string not in quotes in the search field and it was in quotes in the search field.  I've worked around the problem now by searching both with and without quotes.

I know about the various different find/replace functions in LC and wonder why there are three of them that all work slightly differently, but that's another story.  I think the Find/Replace function you get from the Edit Menu when a script editor window is not in focus does what I want for scripts but, as mentioned in an earlier email, it wreaked (wrought?) havoc on my custom properties when I tried to search for a specific one and replace it with a different name.

I've written my own script to globally change the name of a custom property and it's working fine.  I've also realised that looking for strings in a script is pretty complicated because of the many string delimiters that could be present - quotes, comma, open and close brackets, open and close square brackets, etc - so I'll go back to the Find/Replace for that.  I guess I could try using a regular expression but they seem so far removed from the English-like syntax of the rest of LC that I don't think I want to get involved with them!
