Thanks for the response. Interesting -- so you would search, for example, for mysteryttt to find all the books tagged with 'mystery' but not the million other times 'mystery' is mentioned in books? Do I understand that correctly?
Is there any way to make that line one pixel high so it doesn't throw off the spacing so much?
I'm not sure I understand choosing another output profile. I found where that is done but are you saying that it doesn't matter which one I choose, that it can still be used on the Kindle? What sort of things does the output profile effect? Is there one output profile that you recommend? I'm worried about unintended or unknown-to-me effects.
Sorry for all the questions. I do spend hours searching the forum but my technical knowledge is lacking.
