Hey guys. I don't know how to update here so I'll just leave it on discussion.
Since I wanted Map set on Tab I changed two actions that were set as M to Tab. Those where: (ActionName="DebugMenuB",Key=Tab) (ActionName="Select",Key=Tab)
Also after the audio settings part I noticed there was an incomplete (ActionName=Map So I changed to (ActionName=Map ,Key=Tab) and after opening the game this didn't revert back.
Now I don't know which of those 3 did the trick (my bet is on ActionName="Select") but if anyone could double check this and add it to the wiki that would be awesome!
