No. As I explained above, that particular issue was caused because I had him change the Key Combo on the Assist macro to something other than BACKSPACE. He choose [, which is normally assigned to /targetexact macro. He exported, but did not to a /console reloadui, so ISBoxer then sent FTL+[, which the prior ISBoxer Addon registered as /targetexact, so everyone targeted the main. After doing a /console reloadui to load the new ISBoxer Addon, back to the behaviour of no assist.

Typing in /assist CHARNAME on the in game console should work. It is not. This is the issue. /assist CHARNAME does nothing in game (nor /a ).
