I've used such shortcuts for some time and have only hesitated to
include them in the default rc.wmii because they are too long, in my
opinion. I don't like your version, simply because it uses non-standard
grep arguments which and a generally confusing way of doing things.
Also, I'm not a fan of emacs-style keybindings. The two keys should be
next to eachother. I use n and b. , and . are fine, as well.

fn next_tag {
        awk -v curtag'='`{wmiir read /tag/sel/ctl} '
                NR==1 {first = $0}
                $0==curtag { if(getline) print $0
                             else print first
                             exit
                }'
}
fn Key-$MODKEY-n { wmiir xwrite /ctl view `{ read_tags | next_tag} }
fn Key-$MODKEY-b { wmiir xwrite /ctl view `{ read_tags | sort -r | next_tag} }

I won't use tac, because it's a nonstandard utility. I've never had any
problems with sort sorting differently from wmii, but I also use p9p
sort, as should rc.wmii for anyone who has it of 9base installed.

I used to have a separate awk script to pick the last tag, but chose
this approach instead because it was more concise.
