How would I make a catch all keymap?

[zenga]

Willing to make a keymap that I can activate that catches every key I hit on toon 1 (typing, spell casting) and broadcasts it to 2 & 3 as 1 specific key (OEM 7, 1 or 2). Anyone a hint how to achieve this?

D3 boxers enable key broadcasting AND key mapping. The keymapping works, and if there isn't a keymap for the key it will just broadcast it.

that will catch ALL the keys

I was unclear in my OP. What I want is that every keystroke on Account 1 gets mapped to a specific key to client B & C.

i.e. I type my random crap in guildchat in client A, and it' sends '1' to B & C.

Playing the AH on B & C while playing my main toons on A. '1' contains a confirm post macro on B & C.

(if I was to enable keybroadcasting that would result in just cloning what I do on account A to B & C, which is not what I'm after).
