[2020] Frustration regarding key-binds

Originally posted by Calcium Overdrive: Hello community, me and my friends are undergoing severe frustration since the new "press space to exit rappel" patch. The reason to this is that there is no option to rebind that feature as well as "drop down hatch" (when playing as oryx). All of us left-handed gamers are calling for your help :( We need to get this message visible.
Sincerely, me

Hey there! I believe the "Drop Down Hatch" key bind functions the same as a secondary gadget. What's your key bind for that?
