Walkie Talkie ability, where to start ?

[discofever]

I want to make a Walkie/Talkie ability (just like in Firewatch); regarding Input, is there a way to access Player Input in order to catch key presses ?
Or how would you go about it

A walkie talkie would be similar to a flashlight in that it's a generic usable item. I would start with a setup similar to the flashlight and then create a new module that activates when the item is used. You shouldn't need to create any new abilities.
