What was unbound on each of the characters while rebinding (NULL being nothing)

Shift+Back Ctrl+Back Alt+Back Ctrl+Shift+Back
Puntrchi NULL NULL NULL NULL
Myriadone
Btm Right Action 8
NULL NULL NULL
Endlessone
Btm Right Action 8
NULL NULL NULL
Multipleone
Btm Right Action 8
NULL NULL NULL
Variableone
Btm Right Action 8
NULL NULL NULL

After running through the unbinding of Mod+Backspace and then retesting Assist Me (via Assist Me, Interact with Target, and Hotkey 1).

Bind Used Puntrchi Myriadone Endlessone Multipleone Variableone
Puntrchi U X X
Myriadone X U X X
Endlessone X X U X X
Multipleone X X X U X
Variableone X X U


With the rebinding Assist Me now works on:
- Multipleone and Variableone when FTL is Punterchi
- Puntrchi and Multipleone when FTL is Variableone

For shits and giggles I remade the 4 man *one team that was working just fine when I was leveling them through the dk starting area and found that the table looks the same just take out the Puntrchi row and column. So somewhere somehow my team broke the backspace key bind when I added Puntrchi into the mix :/

Anyways I just changed the FTL Assist keybind in ISBoxer to [Num *] and everything works just fine. I'm still confused as to why it broke when I added Puntrchi or why it only worked on certain characters :S
