1. / well always work. and you may choose one other using alt-o/other/command prefix

2) no

3) /help $read, example $read( logfile, ntw, *word* , N )

4) Assuming your not using a big value ie: 23.123456 just multiple it by 1000, to make it 23123.456 , this $calc(23123.456 / 5) = 4624.6912 reprocess at display time to get you 4.6246912
(this is not an effiecnet solution)

5) Some changes on its own if you speced the Normal Text color, or if its ctrl-c color codes you can search and replace them, or if its a mass change then you could reassign the color of the Nth color *thats quite sneaky)
