Just read Kirk's article on code replacements:
http://www.sportsshooter.com/news/1951and I thought I'd share my CR tip that helps answer "how can I speed up my workflow?"
One thing I dislike about CR is that it requires a delimiter character. I understand that the delimiter eliminates ambiguity, but if my CR code is z104, then this is pretty clearly a code and requiring delimiters just adds 50% more keystrokes.
My style of sports shooting is to focus on one athlete. As a result, most of my photos require a single CR where I identify the athlete and usually include some other information like the team. In these cases I place the jersey or bib number in the Caption Writers field (just about any field should work). After I've keyed in all the data, I then use the Stationery Pad to set the Headline field to \{captionwriter}\ and this fills in the Headline field with the CR text.
This leaves me with the jersey/bib number in the Caption Writers field and the CR text in the Headline field, both of which I can use to sort my photos. A sort by headline is an easy way to catch typos in the Caption Writers field as miskeyed jersey/bib numbers will usually have "\\" as the Headline text.
