Hi,
First of all, thanks for the great WM!
Anyway, I have small patch set that allows user to select tags
using Mod1-Left|Right (or whatever user wants to map them)
in case someone is interested. It is similar that was suggested
by Jukka Salmi in thread:
http://lists.suckless.org/dwm/0607/0026.html
but works against latest dwm sources.
Note that if user has several tags selected, only one
next/prev tag is then selected.
