another approach would be to control from pd, which window is in focus
by using 'vis' messages sent to canvasses. you could implement some
keystrokes to navigate through all available windows. this way you
wouldn't have to leave the keyboard for switching between windows and
compared to the built-in window switcher of your window manager, it has
some advantages: 
a) you can access pd windows, that weren't already open; 
b) you can design it for your particular needs, so that only pd windows
can be accessed, that are meant to be accessed. 
then you only need to route the key messages to the window, that last
received the 'vis 1' message. 

this is not exactly what you asked for, but i hope it is useful for you
