I have tried re-mapping the use key to "." aka period button, but what happens is the game only works when it says "Press . to look", then the character looks, but "Press . to use" doesnt work, so I cant interact with objects.
If i remap the key again to another key, then "use" works, but "look at" doesnt work.
Seems like the game is defaulting to using the F button for both "look at" and "use" but when you change the setting it will only change one of these functions to the new button. At least this is the case for using the period key which is what my control scheme always uses in games for the interact button.

I hope this can be fixed in an upcoming patch? I tried editing the controls files but they are encrypted so no luck there :/
