Newbie help

Hey guys I’m quite new to UE4 and need some help for a university project. I want to add a bunch features but have not really sure how so any advice on how to build any of these would be great. -Using the mouse wheel while inspecting an object to zoom in or out -object highlighting and how to change the colour once interacted with -How to create a noir/monochrome filter that can be toggled via a key binding -Adding flavour text to an object that appears during interactivity
