How to properly keybind as a sniper ?

[Bonappetit 117]

I decided to seperate my binds as a sniper but I firstly wanted to hear your thoughts on it. I would like to bind better my options for zeroing, hold breath and aim down sight. At the moment I only have zeroing rebinded to my two thumb keys on my mouse. I could really use a bit help on this matter as I never played a game with this many options. Honestly I could only think of removing default left Ctrl bind and binding either hold breath or aim down sight but perhaps some experienced sniper in this game could help out.
