Basically it's just like any other shell .*rc. It sets some environment
variables for stuff, a bunch of aliases and some functions i find useful
myself, or am too lazy to throw away. Nothing really ksh-specific, except
maybe some of the functions i wrote use ksh-stuff like arrays, but that's
not really ksh-specific as well. You could use google to find any .*rc for
sh-like shells and copy those (or get a copy of unix power tools, it's a
nice book to make you feel at home in a shell)

ps. these functions i probably use the most :)
alias d="do_in_bg dillo"
alias x="do_in_bg xpdf"
alias ff="do_in_bg firefox"
#do a program in the background:
do_in_bg() {
"$@" > /dev/null 2>&1 &
}
#open a webpage from disk, like: $cd /usr/share/doc/en && htm
#to look at all the (english) freebsd-docs :)
htm() {
set -A stuff $(find -L . -name "index.htm*" -print)
(for ((i=0; i < ${#stuff[*]}; i++)); do print "$i \t: ${stuff[i]}"; done) | $PAGER
read x && d ${stuff[$x]}
}
