1) first you have to open f1 in game a bar will pop down from the top this I where you type in the command for binding
keys
2)second you start of the command with "bind" then a space the key you want for example "r" so this is saying you want to bind the key "r" too
3)next is what you want the key to do when you press it so for example /r is for rescue in ddrace which has rescue enabled so you would say "say /r" this means when you press "r" because you have binded the key and command together it will
activate rescue
4)so the whole command should look like this "bind r say /r" but without the " "
5)that's it its done press f1 to close it and start playing
(extra thing) when your playing a map without rescue enabled and you want to be able to kill yourself quickly in game if you press Esc and controls at the bottom right it you will see respawn if you click this and select a key you want for it you will be able to reset quickly. I have also tried to bind kill but that doesn't work so this will allow you top reset quicker
