Ok. For anyone interested, I changed my p9p rio key.c:
*** key.c_orig	2012-11-03 18:59:41.040071847 +0100
--- key.c	2012-11-04 10:41:27.853606153 +0100

  	for(i=0; i<num_screens; i++){

  }

which now opens xterm (xt is my xterm with unicode locale on) on
pressing alt-t and runs dmenu_run (related to dwm) on alt-r.

I missed these two shortcuts heavily.
(warning: I just added the lines by means of observation; I do not
really know what stands behind those XGrabKey and alike functions.
Nonetheless it now does what I want.)

Also I want to ask if someone noticed that p9p rio for some reason
precludes e.g. shuffling of firefox' tabs (both within one window and
between windows). Running twm instead of rio helps in this respect.
