how to change keys in TMO
 

I would like to create a command so that can go straight to test depth in lieu of manually ordering the depth on the gauge or hitting the D key.The D key would be fine but when do that the dive alarm goes off, well that kills immersion a bit when say youre running silent after an attacking.Ordering t manually is a problem because when I click on 300 feet and the diving officer says 300 feet, the boat gets leveled off at 299 feet usually and its a pain.I want to keep the dive button for when ready to dive but a key to take boat to test depth fast with a large down angle, would be great.

Anyone have the know how to do this? Thanks in advance.
