Wolves of Steel: Four Bearing Question re: "Z" hotkey

[roccom]

I'm playing WoS and am trying to do real navigation and the four bearing method.

However, the tutorial video explains that you should spam the "Z" key to get the bearing readout, but in the mod that is the rig for silent running hotkey.

What is the command (mouse clicks) to have your hydrophone operator tell you the bearing of the locked contact?

Alternatively, I downloaded the mod to remap hotkeys, but I cannot figure out which actual *command* I'm looking for to map to a key, so the name of the command would also help.

(Thanks in advance, and sorry if this is the wrong place.)
