Duplicate keybinds

What is the point of having duplicate key binds for most of the functions. Like there is the leap/jump/interact and there is a seperate key just for leap. Which doesn’t work anyway so it’s useless.

Leap only works provided you have enough stamina, which is the grey bar at the bottom of your screen

Still doesn’t explain why there are multiple keybinds for it.
Also I thought that was the sound meter for when the FT can hear you.
