ME:LE ME3 "The key 'Tab' is a constant key and cannot be rebound."

Hello,

i'm unable to use these keybinds in ME3 from Legendary Edition.  Tab, B, T are impossible to use. I got an error message : "this key is unique and can't be assigned".

I guess this is a bug because of multiplayer mod that doesn't exist anymore but still lock the keys... Please fix this.

The keys B and T are also locked in my game.

I found a workaround thanks to this Reddit post.

1. Download the ME3 coalesced utility/ 
2. Follow the instructions in the reddit post to find the Tab binding and remap PC_Push_to_Talk to something else (e.g., F10)
3. Use the utility's Find feature to find all references to "binding" and then every time "B" or "T" is listed, remap them to something else (e.g., F11 and F12).

Well I have a similar problem, but the key is 'p'
since I'm playing left handed, i would use that as 'move forward'
Anybody have an idea understand how to make this possible using the ME3 coaslesced utility?

@krissirge

I think "P" is blocked under: bioinput.ini > engin > playerinput > bindings

Remapping "P" here to, for example F9, should allow you to remap the key normally in game.

Actually might be that the Expanded Galaxy Mod actually makes this key constant.
Seems like it raises/lowers the gun constantly, which is a feature there!
