There is no such feature as the developers didn’t implement it.

Also, you might be confused about the “mods” we are making. Mods here are only limited to the custom hangar, custom missions, and custom sounds changes - and not more than those! Other client-side modifications are strictly prohibited. So custom keybinds are just a no.
