I have forgotten the keys for this action. Thought it was left shift + Q/D (azerty keyboard) but it does not work.

I got all the beakers but the achievement didn't activate, did anyone have the same problem ands solve this?

I have played through this game three times fully resetting each time and still can not get this. I love the game, but not having only one achievement is really annoying. Can anyone help with this?

I accidentally started a new game, can I get my save back / go back to my old checkpoint in any way?

I've accidentally set my colour change button to esc and now i can't undo it. I can't use the map, start a new game do anything else that requires going to menu. Can someone please explain how to fix this issue? I don't mind losing my save. Thank you in advance....
