I'd like to know more about the Transcript Dictionary search function.

Essentially, that's what I've ended up doing so far, except I'm using the
lineoffset function in a loop, having it look for the return character + the
first character of the line(s) I'm searching for. It's working well enough.

I looked at that command. I actually need the line numbers...not the lines
themselves. The line numbers serve as indexes to additional data.
