1. If I have a M-by-N table with entries like this (you may recognise the example ;)...
... {. curlylfdot {: curlylfco {:: curlylfcoco } curlyrt ... how do I neatly slice off the first 3 columns (say) into a boxed list of tally M to serve as a lookup index? Ditto any given field, i.e. set of columns? I'm often doing it, but a different way each time, and the methods I use are cumbersome. 2. Is there already a slice'n'dice cookbook on the wiki, to give quick answers to questions like this?
