I have used AutoHotKey with PzC for a couple of years; in fact at this point I can't really imagine playing PzC without it. It is actually very easy to use, although there are a couple of quirks; there is a thread on this topic:

You should be able to download the scripts I used from that thread; if it doesn't work let me know and I will send it to you. I use Ctrl-A for Assault. Here is my blankbox file listing all the hotkeys I use (standard ones on top, AutoHotKey ones on the bottom):
The most-used are Ctrl-A (assault) and Ctrl-X, Ctrl-Y (move to bottom/top of stack).
