Stole your link and added it to the wiki!
We'll honestly I have no real experience how good it works out, to box EQ2 with HKN, but by reading the thread I think it should be possible (although, the hotkey-definition might be a little bit complex).
For more infos, maybe ask at the HKN board directly for some help if you want to try it out, normaly Freddie and some other users respond quite quick ;)
