About auto mapper

The default directions defined are:
n (north), s (south), e (east), w (west), ne, se, nw, sw, u (up) and d (down)
but sometimes I want to auto mapper can record some special commands, such as
nd(northdown), eu(eastup), etc.
Could you tell me how can i do?
Thank you!

You can add it to the special moves dialog:

Actually I wrote a nice plugin that does exactly that. Email me if you want it.
