Hello, nice community you got here

Now on to the question

I have set-up octopus to link my 2 computers together. under "server" tab I clicked the "toggles" button and set key broadcast to my keyboards ~ key. so when I press the ~ key it captures my second computers keyboard.
now for my question, I have f1-f4 = party members 1-4 then cast renew,
f5-f8 = cast flash heal on party member 1-4,
f9-f12 = cast greater heal on party members 1-4...
But when I push the ~ key and push f1 to cast renew on party member 1, my melee switches target to party member 1.. I then have to either tab or right-click to start attacking the mob again on my main melee character.

is there a way to push the ~ key and only have the secondary keyboard register keys so I can cast my spells and not lose my target with my melee character? I am aware I could just change the keybindings on the melee to not use f1-f4, but I am so used to using it to target my party members. My 2-boxing characters are a priest and shaman and the priest just follows the shaman around and heals when needed.

also I did search and came up with nothing. so if this is in the wiki and I missed it I apologize..

thanks for the help
