[MiRai]

hmm - do i actually gotta make new key maps ? i use R as my interact with target, do i have to make 2 new keys or just leave them blank/copies without a new bind in them

I doubt that you'll want to make any new Key Maps, but you may need to make some new Mapped Keys—It really comes down to what you want to press and how you want it to be handled.

However, right now it sounds like you could easily change the behavior by not choosing to use "Auto-Interact," which is a setting that needs to be manually enabled during the Wizard, and afterwards can be adjusted in the "Virtual Mapped Keys" tab of your Character Set.
