Change Witcher senses to toggle instead of hold?

[quinnsimmons]

Is there a way to, or would somebody be willing to create a mod to, change the Witcher senses so that you can toggle them on or off instead of having to hold a key down? I find myself looting lots at a given time so it gets really annoying to hold down the key.

This. Also no zoom in or less zoom in while senses are active. I can't see s#*! indoors because of it.
