I use Hotkeynet and i use 2 wow account at the moment. Very new to this, dont even have a level 85 yet on my second account. Because i only use 2 account atm, so i have the keys, so that if i press 0-9 they will be send to both acc. Numpad 0-9, will send 0-9 to my slave. Arrows send wsda to my slave only. Why i do that way and not setting a secondary key is, so i dont need change my keybindings all the time, if i change who is master and who is slave. But maybe there is better ways.

Anyway my question is, if i have healer as my slave. What way would it be easiest to target and heal. I use 2 acc, but in party can be more members, my bro is also dual boxing, so at least 4 in a party. As it is now, i need to press a button F1-F5 (i use in combination with ctrl, that is only send to slave) and then on numeric keybad the healing spell. I saw a video where they used grid, but should work with healbot as well, that show on the mains screen, even that the healer is slave. But think that works only with ISBoxer.
