Inspired from THIS thread, i've modified the keybinding Scheme that i use, because i always forget which keys i've mapped with which Function and want to share it here. Maybe it helps the ones that are new to rF2 or also others. This Scheme shows the default Binding. (If i forgot something or something is wrong, please post it here)
Don't some require Ctrl key and some are just pressing the key? For instance, framerate is Ctrl-f, yet the numpad camera keys just need the numlock turned on and you don't have to press Ctrl-+ to advance to the next car. Also, you can use 1 and 0 for voting yes/no while driving. No control key, as I recall.
I have seen that i have the picture from redapg, that he has posted and that is not shown here anymore. I think it still can be helpful. Here it is.
