IIRC, there's the roguelike keyset, which should work in Rogue:
y k u
h * l
n j m
It's a bit awkward, and might be inacccurrate (I think I reversed
j/k), but it Rogue should still have that.
If it's not that, you may have to get the source code for Rogue and
try compiling...
There are a couple of versions at
http://www.roguelikedevelopment.org/archive/index.php
Not sure if they work without a numpad though.
