Find and highlight text in other app using regular expresion

[stupomer]

Thanks for looking into this. The second version had my attempt to calculate the range if(replacetext) as well as else (not replacing text) but it probably needs some more tweaking, as you suggest. Also I could just call RichEditHighlight as you also suggest.

One thing is that if RichEditHighlight applied one set of colors to text/background, it seems it won't work a second time. I know how to turn off bold/underline/italics in order to reapply formatting, but couldn't achieve the same with colors (it just went to black on black). Any thoughts?
Thanks again!!!
