hi piggy,

sorry about the slow response.

unit187 put an extensive guide for AHK together here:

if you are unsure of scripting and would rather just get up and running, there is keyclone here:
http://www.dual-boxing.com/forums2/viewtopic.php?t=883

keyclone is easier to set up and has a few tricks AHK doesn't have. on the other hand, keyclone has a one-time $10 price tag (all updates free).

i might be biased as i wrote it.. and continue to update it. my goal has been to get people up and multi-boxing in minimal time... reducing the hardware cost along the way. you should be able to find plenty of references to keyclone using 'search' here.

if you have any questions, just spend me a PM.
